Stockouts lead to unattended sales, which mean loss of income. This endangers the place of the MSBs in the industry. This paper aims to prove that proposing a supply management model will reduce the number of lost sales due to stockouts. For this study, we analyzed three key processes (purchasing, storage and distribution), where we identified problems such as incomplete shipments and unfulfilled POs and replacement requests. To prove the viability of our proposal, a pilot was carried out in a pharmacy that has five dispensing premises and a central warehouse, which improved its stock availability from 82% to 89.5%.

Finally, in the fourth chapter, the simulation is performed with Arenas software, where it was shown that increasing the probability of stock spares from 90% to 96% efficiency of 91% was obtained, and the economic evaluation was conducted in the optimistic, moderate and pessimistic scenarios obtaining indicators for the project. / Trabajo de Suficiencia Profesional

Historically, hydrologic models have been available only on mainframe computers and have therefore not been used by local water managers to support daily decisions. The development of the microcomputer presents an opportunity for that to change. Mathematical models of soil moisture and river routing are selected, developed and tested for use on a microcomputer as an aid to local water management. The models are then integrated with an appropriate data base in a computer program written for a microcomputer. The result is a Decision Support System for local water managers. In order to evaluate the feasibility of using the Decision Support System, an application of the program to a small hypothetical river and irrigation system is carried out. The speed of execution indicates that the use of the Decision Support System on this class of computer under the present configuration may be possible if software or hardware changes can reduce data transfer times to and from disk.

A research report submitted to the School of Civil and Environmental Engineering, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Master of Science in Engineering, Johannesburg, 2017 / Human beings depend on water not only for life itself but also for their economic wellbeing. Water resources play a cardinal role in the creation of everything that human beings produce. Post-apartheid South Africa is in the throes of incredible challenges. One of the more important challenges is access for all citizens to basic services. South Africa is doing this against a backdrop of strongly differential servicing that is its apartheid legacy, which has prompted many commentators to label South Africa a country of two worlds, more specifically, a developed world component and an impoverished developing world component. The challenge with respect to water is to ensure universal access in the context of the added hurdle of South Africa being a water-scarce country. The local municipalities of the Eastern Cape have been facing a number of challenges in the provision of clean, portable water to their communities. This has resulted in inadequate provision of water, meaning that not all communities have access to clean water 24 hours a day The overall objective for this study is to contribute to the body of knowledge available to the water sector about the management of sustainable water supply systems in municipalities, and determine the factors that have undermined the sustainability of water provision at a local government municipal level in the Eastern Cape Province of South Africa. In this research, the effectiveness of local governments, which act as water services authorities (WSA) and providers of water to the rural communities, is examined. To this end, a comprehensive literature review was conducted and data gathered to discover why there has been a failure in the provision of clean drinking water. The results of the research illustrate that institutional incapacity in rural municipalities and widespread poverty serve to undermine the sustainability of the local government sector and lead to breakdowns in services delivery. Measures are proposed that can be adopted to improve the current approaches of water supply in local municipalities. / CK2018

Water is both a human right and a valuable commodity. Access to water for the rural poor is an international development concern that has been highlighted by the Millennium Development Goals adopted at the Millennium Summit in 2000 in Dublin, Ireland. South Africa's Free Basic Water policy is the government's response to assuring access to water for all - especially those who cannot pay. The policy, however, is required to work within an economic framework that promotes cost recovery and privatisation. The Free Basic Water Policy was officially implemented in July 2001. The policy was rolled out in most urban areas on or near this date. However, in rural areas it has proven much more difficult, and there are many areas that have not yet seen the implementation of Free Basic Water (FBW). This is partly due to varying financial, technical, political and logistical problems at the local and district municipality level. This research investigates the current situation in rural municipalities, looking specifically at FBW policy, institutional arrangements, operation and maintenance costs, cost per capita and affordability in relation to the Equitable Share allocations. Five case studies - compiled through interviews, document analyses, Participatory Rural Appraisal, and workshops provide a broad scale research base from which to analyse the current implementation of FBW in rural municipalities and ascertain whether this policy is affordable at this level. Water Service Authorities (WSA) are at varying levels of implementation, with few having a fully operational policy that is reaching rural areas. A costing exercise revealed that the service delivery price of water varies, but does follow a trend. From this trend a benchmark cost per capita of R5.84/month was determined. This price, although low, is not currently affordable in some municipalities due to insufficient government grants from National Treasury. These grants are fundamental to the sustainability of FBW and the situation must be resolved if FBW is to reach its target market - the poorest of the poor. The mixed success in the implementation of Free Basic Water in rural areas of South Africa should not be taken as indicative of future trends. As the local government transition to newly devolved powers and functions is completed, the capacity at this level to resolve the challenges is more likely. Subject to the continued strength of the South African economy, this policy could be a solution to the historical failure of service delivery to rural areas. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2004.

This project developed a model for effective asset management drawn from successful programs in the United States, Australia, and New Zealand. Asset management practices were examined at the City of Ontario Utilities Department; a medium sized utility, and also at the Rainbow Municipal Water District, a small sized utility. Gaps between the ideal model and the existing practices were investigated.

Most contemporary South African businesses are facing tough times. This is the result of emerging trends such as intense global competition which requires businesses to be quick, agile and flexible; new technology available to any business willing to adopt it; more advanced customer expectations and the implementation of new strategic, proactive management approaches. In fact, many of them (including wholesalers) will succeed only if they can successfully integrate strategy, processes, business arrangement, resources, systems and empowered workforces to render their core business effectively. Choosing suppliers and purchasing products are critical wholesaling activities and often determine the success of wholesalers. Wholesaling institutions, however, vary considerably in size, activity, style of business, types of products provided and services rendered. These variables imply that the complexity of wholesaling activities differs. It therefore stands to reason that the level of sophistication with which these wholesalers manage their purchasing, sourcing and supply activities may differ. The level of sophistication with which wholesalers manage their purchasing, sourcing and supply function may vary from traditional management approaches to advanced integrated management approaches. The use of the new management approaches by businesses is a vital instrument in facilitating change. This leads to the development of more focused, specialised and high-performance organisations. Manufacturers are not geared to deal directly with the thousands of small retailers and therefore use wholesalers for this function. Wholesalers provide a vital link between manufacturers and retailers, and play a pivotal role in efficiency of the whole supply chain. Adapting to the supply chain management approach may thus mean the difference between success, failure and the continued existence of the wholesaler in supply chains. This research study was undertaken to determine to what extent wholesalers in South Africa have adapted to new demands and developments in their purchasing, sourcing and supply functions. Secondary to this objective was the need to (1) investigate the scope of wholesaling, with reference to the global and South African context; (2) investigate the concepts of and the evolution of purchasing to strategic sourcing as part of the broader supply chain management approach; (3) analyse the scope and concept of supply chain management; and (4) determine the purchasing, sourcing and supply management approaches used by the wholesale sector in South Africa. The study was conducted in several phases. Firstly, a literature research was conducted to gather and integrate secondary data in order to (1) expound the definitions, importance, types, activities and trends of wholesalers; and (2) investigate the development of purchasing to strategic sourcing and evolution of supply chain management, and to give an overview of purchasing, strategic sourcing and supply chain management. Secondly, a questionnaire was compiled containing all the relevant issues identified in the literature research to enable the researcher to establish how far South African wholesalers have advanced in adopting new approaches to managing the purchasing, sourcing and supply function. This questionnaire was pretested on two respondents to verify its validity, before proceeding to the next step. Thirdly, a letter and the refined and tested questionnaire were mailed to all the wholesalers identified to be involved in the survey, informing them of the research study and soliciting their cooperation. The letter requested the participants to return the questionnaire via facsimile. Fourthly, to improve the response rate, after the date for returning the questionnaire had lapsed, additional questionnaires were faxed to all the respondents who had not completed the initial questionnaire. The literature research established that the new demands and developments facing wholesalers in managing their purchasing, sourcing and supply function are a reality. Wholesalers are confronted with a variety of challenges concerning these demands and developments which is jeopardising their vital role in the supply chain, and they need to adopt a more sophisticated method of managing these activities, not only to ensure their own survival, but also to lower the costs of the wholesale operation, and ultimately allow an increase in shareholders' wealth. The empirical study, however, clearly indicated that South African wholesalers are still significantly focused on the tactical aspects of purchasing, incorporating only a few aspects of strategic sourcing and supply chain management. The position of South African wholesalers regarding the level of sophistication in their management approach to the purchasing, sourcing and supply chain management approach can be regarded as a mechanical approach, with proactive tendencies. It is therefore clear that South African wholesalers have not adapted to the strategic sourcing and supply chain management approaches, and need to prepare themselves for this change - or risk failure. / Business Management / M.

Thesis (MBA)--Stellenbosch University, 2005. / Some digitised pages may appear illegible due to the condition of the original hard copy / ENGLISH ABSTRACT: Water is essential for life. Like the very air that surrounds us the omnipresent and indispensable qualities of water pervade throughout all of our lives. For reasons of health, community and trade the beginnings of all civilisations were proximate to the mighty rivers of the world. In a rapidly expanding global village, the priority for our future is to secure the management of increasing levels of water demand, given the finite natural cycle that all water is subject to and derived from; the hydrological cycle. The focus of this papers investigation is how best to allocate the value of water through the relatively nascent developments of water markets. The premise of utilising markets for allocative efficiency is suitably ingrained in the workings of many societies today, and the need to treat water with commensurate value and avoid waste is encapsulated in the Dublin Principles, where #4 states; 'Water has an economic value in all its competing uses and should be recognised as an economic good'. Which in isolation has merit, the legacy of state water management is usually associated with underperformance at best or incompetence and corruption at worst, and therefore the introduction of market mechanisms to provide water with allocative efficiency and true value, should be a positive undertaking for change. However the requisite conditions for proficient markets and perfect competition; which primarily include, that all agents are buyers and sellers, for a homogeneous product, with perfect information, without externalities, after the full and fair assignment of property rights, where all goods and services are private goods, and where transaction costs remain close to zero; would seldom be applicable to water. The many idiosyncrasies of water inhibit the application of competitive markets. Water could easily be defined as a public good with riparian rights, subject to a range of social and environmental externalities, whilst incurring high structural entry costs and remaining subject to the problematic vagaries of the natural supply cycle. Demand profiles also give water a heterogeneous definition, as domestic uses include both sanitation and drinking water, whilst various levels of quality are required for industry and agriculture, and even recreation. This paper seeks to define those factors that both warrant and limit the introduction of market functions to water management. The premise of this paper remains the search for better ways of valuing water, and how to incorporate fully the foundations of the environment and social criteria of health, and poverty reduction within these economic considerations. The conclusion defines a premium / discount solution to market traded water prices, which internalises these factors. / AFRIKAANSE OPSOMMING: Water is noodsaaklik vir lewe. Net soos die lug wat ons omring het water ook alomteenwoordige eienskappe wat In onskeibare deel van ons lewens vorm. Die ontstaan van alle beskawings is te vinde in die nabyheid van groot en gevestigde riviere vir redes van gemeenskaplikheid, gesondheid en handel. Vandag se geintegreerde en snel-groeiende samelewing met sy toenemende vraag na water, noodsaak 'n toekomsgerigte benadering om waterbronne te bestuur gegewe die vaste water natuursiklus waar water vandaan kom en bewaar word in. Die fokus van hierdie studie is om die beste metodes te vind vir waterallokasie met verwysing na die ontwikkeling van water markte oor die eeue. Die gebruik van die markstelsel om water effektief te allokeer is die grondslag van baie samelewings vandag. So erken die Dublin beginsels die noosaaklikheid om 'n waarde te plaas op water beklemtoon dat dit nie vermors moet word nie. Beginsel #4 bepaal: "Water het 'n ekonomiese waarde in al sy vele gebruike en moet ooreenkomstig erken word as ekonomiese saak". Die bestuur van waterbronne deur 'n owerheid word gewoonlik vereenselwig met 'n nie-optimale of selfs korrupte onbevoegdheid. Hier behoort die bekendstelling van mark beginsels om 'n waarde en nut op water te plaas dus 'n positiewe ontwikkeling te wees. Tog is dit ook duidelik dat die vereistes vir 'n effektiewe mark; alle agente is kopers en verkopers, 'n eenvormige produk, deursigtigheid in informasie, geen eksternaliteite, erkenning van besitreg, alle goedere en dienste is privaat goedere, transaksie koste is naby aan nul; nie volkome toepasbaar is op water nie. Die eenvoudige asook komplekse aard van water verhoed dat standaard markstelsel en beginsels van kompetisie eenvormig toepasbaar is. Water kan ook maklik gekategoriseer word as publieke goedere met gemeenskapsregte, wat dit dan onderhewig sal maak aan verskeie maatskaplike en omgewingsmaatreëls, hoë toetrede kostes, en logistieke probleme van die verskaffingsiklus. Dit is egter die vraag na water wat defineer dit as heterogene produk met huishoudelike gebruike vir beide persoonlike verbruik asook sanitasie, terwyl doelgerigte gebruike in landbou, handel en nywerheid ook spesifieke kwaliteite kan vereis. Hierdie werkstuk beoog om die faktore te defineer wat die bekendstelling van 'n mark stelsel vir water bestuur daarstel en ook beperk. Die uitgangspunt van hierdie studie was om maniere te vind vir beter ekonomiese waardasie van water en dit dan te kombineer met die fondasies van die omgewing, maatskaplike & gesondheidsmaatreëls, asook die toeganklikheid van basiese dienste aan almal.
