Modelling and simulation of production-marketing systems

Apampa, Olufunso Olatokunbo January 1984 (has links)
Three aspects of complexity in a Production-Marketing System are identified, namely the Model, Decision-Making and Behavioural complexities. Control theoretic and other techniques are reviewed in the context of their contribution to the resolution of these complexities and the modelling and simulation of the PMS is also viewed in this light. Several analytical models of a consumer-durable marketing system are developed, reflecting various assumptions of market conditions ranging from the single-product constant-decision marketing system to the multiproduct variable-decision marketing system, the latter explicitly accounting for price, advertizing, distribution and quality decisions for each product, repeat purchase dynamics and the tastes, income and population of consumers. A production system model is also developed involving a multiple final product, multi-stage production process, permitting the backlogging of demand, variation of production rate by variation in workforce levels and overtime and subcontracting of manufacture of intermediate products. Computer simulatiors of the marketing system based on the models developed and using assumed data are carried out. An optimization routine is used to generate the variable decisions. The variable-decision marketing model is combined with the production model and the resulting limited capacity PMS is simulated using assumed data. The simulation results are presented graphically and attention drawn to their realism. The use of the PMS simulation programme as a nucleus for a comprehensive PMS simulation and control package is commented upon.

TPM Maintenance Management Model Focused on Reliability that Enables the Increase of the Availability of Heavy Equipment in the Construction Sector

Palomino-Valles, A., Tokumori-Wong, M., Castro-Rangel, P., Raymundo-Ibañez, C., Dominguez, F. 06 April 2020 (has links)
The purpose of this paper is to present a maintenance study focused on total productive maintenance (TPM) and reliability-centered maintenance (RCM). Its approach is based on the first pillars of TPM, preventive and autonomous maintenance, as well as the FMEA analysis of RCM for maintenance analysis, which was conducted in this study. The implementation of TPM was successful in that various preventive maintenance (PM) policies assigned to the assets were implemented and it was demonstrated that TPM application in the construction industry could reduce the excessive accumulation of maintenance with the same effective optimization, and with support from RCM analysis and its heavy equipment systems analysis. Excessive corrective maintenance accounts for high investment and delay rates in work times of the assigned project. Traditional methods of availability guarantee, such as reactive or routine maintenance, are insufficient to satisfy a heavy equipment maintenance plan; therefore, what is called for is the systematic application of RCM and TMP because they allow the selection and application of effective PM tasks. An approach that develops and thoroughly analyzes the strategies of continuous corrective and PM is used with an atmosphere of uncertainty and with operational data limited by criticism. Results show a 90% improvement in availability. / Revisión por pares

The Study of Knowledge Management Model-System Component Research

Lee, Wen-Hsin 26 June 2001 (has links)
What is the competency advantage of company? What is the niche of company? These are the important question in management field. In this knowledge society, company¡¦s successes depend on company¡¦s special and particularly intellectual capital. Take Microsoft as an example, it¡¦s book value is not its software factory, actually it has no software factory, Microsoft¡¦s book value is constitute by its goodwill, person computer operation system stander, and the ability to form an alliance with other companies. The goodwill and abilities are Microsoft¡¦s intellectual capital. So, knowledge had become the most important active and result in economic actives. How to manage knowledge is the most important work for management in this century. Because the knowledge management becomes more and more important, many research and theses begin to study about knowledge management, and many software suppliers have developed it¡¦s own knowledge management framework and solution. The market of knowledge management software and knowledge management service keep growing, books and theses about knowledge management also create many new ideas, and all companies began to realize knowledge management is an important direction for company¡¦s development. The complete knowledge management including many components, and knowledge management involve many issues about company, including company¡¦s strategy, employees, technologies¡Ketc. So, this thesis studied the theses about knowledge management and did many case studies. And interviewed some companies, which carried out knowledge management in Taiwan and compared the cases with theses. By the comparison between cases and theses, this thesis tries to find some contribution for knowledge management. And this thesis wants to provide useful advices for companies, which want to carry out knowledge management.

Challenges for mid-level commanders in the South African National Defence Force : management model and training needs

Edwards, T., Geldenhuys, A. January 2007 (has links)
Public Article / The Constitution of the Republic of South Africa, 1996 (Act 108 of 1996) and conclusive Acts record that effective human-resource management, career-development and training practices must be cultivated to maximise human potential. The unique nature and wide range of activities of the South African National Defence Force assign exceptional demands on the management expertise of military commanders. Therefore, the importance of effective training and for the purpose of this article, effective management training for mid-level commanders is indisputable. Against this background, a new management model is presented and the resulting training needs are empirically investigated in this article. Both qualitative and quantitative methods were used in the survey, targeted 165 mid-level commanders in the South African National Defence Force. The empirical results of the study suggested that the existing management training for mid-level commanders fails to meet expectations primarily because of the non-existence of an appropriate management model. Thus, the article present a contemporary management model as foundation for management training of mid-level commanders in the South African National Defence Force. The management model also sanctions applicable standards for the development of management skills and appropriate competencies of military commanders.

Study on Architecture-Oriented Transmission line and Substation Affairs Management Model

Gao, Da-Jin 21 June 2009 (has links)
Electricity construction is required for a country¡¦s fundamental economic development. It provides the needed power and plays an important role in modern society. In order to construct a complete electricity system, Taiwan government will launch the 7th electricity transmission and distribution project in the whole country starting from the year of 2010. The transmission and distribution construction is an interface to transmit high voltage electricity in Taiwan and will take long time to complete. Based on the guidelines of Executive Yuan¡¥s Public Construction Commission, the construction shall focus on material management system; coordinate, monitor and examine the project; review by routine and check on site; integrate technology and experts from the production field to raise the execution effect and process quality. Construction of transmission and distribution consists of substations and circuits. The construction methodology will determine if the construction can be or not completed on time. With reference by managerial and operational scopes of some enterprises, this thesis sets up Architecture-Oriented Transmission and Substation Affairs Management Model, abbreviated as AOTSAMM, to describe the whole picture for the transmission and distribution project and further to achieve the aims on controlling schedule, raising knowledge management, etc. AOTSAMM contains the architecture of transmission and distribution construction. It not only describes the organizational structure and organizational behavior in enterprise value chains, but also integrates with technology application systems. With duplicating and expanding capabilities, AOTSAMM will easily apply to other electricity system and create contemporary enterprise excellences.

Building partnerships as a key strategy in developing an event management model for an international dance event : a case study of the 2008 WDA (World Dance Alliance) Global Summit, Brisbane, Australia

Liao, Shuyi January 2009 (has links)
With the increasing growth of cultural events both in Australia and internationally, there has also been an increase in event management studies; in theory and in practice. Although a series of related knowledge and skills required specifically by event managers has already been identified by many researchers (Perry et al., 1996; Getz, 2002 & Silvers et al., 2006) and generic event management models proposed, including ‘project management’ strategies in an event context (Getz, 2007), knowledge gaps still exist in relation to identifying specific types of events, especially for not-for-profit arts events. For events of a largely voluntary nature, insufficient resources are recognised as the most challenging; including finance, human resources and infrastructure. Therefore, the concepts and principles which are adopted by large scale commercial events may not be suitable for not-for-profit arts events aiming at providing professional network opportunities for artists. Building partnerships are identified as a key strategy in developing an effective event management model for this type of event. Using the 2008 World Dance Alliance Global Summit (WDAGS) in Brisbane 13-18 July, as a case study, the level, nature and relationship of key partners are investigated. Data is triangulated from interviews with organisers of the 2008 WDAGS, on-line and email surveys of delegates, participant observation and analysis of formal and informal documents, to produce a management model suited to this kind of event.

Současná dynamika krajiny NP Šumava / Recent landscape dynamics of the Šumava NP

Janík, Tomáš January 2016 (has links)
The disturbances are processes, which change the landscape (Bengstsson et al., 2003). In Central European mountains spruce forest, windthrows and subsequent bark beetle (Ips typographus) outbreaks are the most important (Bengstsson et al., 2003; Brůna, 2013; Čada, 2013; Fischer et al., 2002; Matějka, 2013) This scenario was taking place in the study area - the Šumava National Park between 2006 and 2012. The objective was to analyse changes in the land cover caused by the disturbances. The land cover flows were used. The Land cover flows describe changes within land cover types: the area of change from one type into another (Martinez-Fernandez et al., 2015). Layers of the land cover for each year were created; they show the changes mostly in forested landscape. These fourteen-land cover types layers were input into analysis in the Land change modeler for ArcGIS (Clark Labs, 2015). The most important land cover flows were set and further analysis of evaluation in five spatial frames (Physical - geographical typology, Aspect, Elevation, Ecological conditions, Non-intervention and intervention management) were undergone for deeper knowledge about spatial factors of distribution. The Kyrill windthrow in 2007 caused a creation of windfalls (4.73 km2 ), predominantly made from damaged forested area (3.07...
