Backlog limitation system in Commercial Carrier hubs : Leveraging statistics techniques to limit the amount of backlog and late deliveries / System för begränsning av eftersläpning i kommersiella Carrier-hubbar : Utnyttja statistiktekniker för att begränsa mängden eftersläpning och sena leveranser

Spatafora, Roberto January 2023 (has links)
The main goal of Commercial Carriers is to deliver packages respecting the promises made to customers. Therefore, backlog prevention systems play a crucial role considering that backlogs would prevent CCs to reach their primary objective. This work aims at analyzing the state of the art of current available solutions to overcome these limitations, and, on top of those, a new approach is proposed. Then, the new proposal is evaluated and compared to already deployed solutions. The mechanism analyzed in this thesis aims at reaching, through the use of statistics, comparable results to ML solutions in terms of accuracy, but requiring less computational resources. To achieve this, the proposed methodology relies on a statistical model that does not need to be trained and executed, as typical ML models. As a consequence, one of the main benefits is the speed of execution: requiring less than 30 seconds, about 25 times faster than ML approaches. Our findings show that our approach requires about 15% of the data other solutions need: this is a significant advancement with respect to the current state of the art. This constitutes an additional benefit in terms of cost savings for tech resources, both in terms of data storage and program execution. Results prove the effectiveness of the proposal, with 80% accuracy, about 10% lower than averages ML approaches. Key point is the difference in the approach, for which is worth to evaluate the trade-off. Considering the effective low frequency of events that negatively impact the performances and result in backlog, the proposed approach would be valid for everyday scenarios but it would be still advisable to rely on even more accurate technologies during particularly intense periods. / Huvudmålet för Commercial Carriers är att leverera paket som respekterar de löften som ges till kunderna. Därför spelar system för att förebygga eftersläpning en avgörande roll med tanke på att eftersläpningar skulle hindra CC:s att nå sitt primära mål. Detta arbete syftar till att analysera det senaste inom nuvarande tillgängliga lösningar för att övervinna dessa begränsningar, och utöver dessa föreslås ett nytt tillvägagångssätt. Därefter utvärderas det nya förslaget och jämförs med redan implementerade lösningar. Mekanismen som analyseras i denna avhandling syftar till att, genom användning av statistik, nå resultat som är jämförbara med ML-lösningar när det gäller noggrannhet, men som kräver mindre beräkningsresurser. För att uppnå detta bygger den föreslagna metodiken på en statistisk modell som inte behöver tränas och utföras, som typiska ML-modeller. Som en konsekvens är en av de största fördelarna körhastigheten: kräver mindre än 30 sekunder, ungefär 25 gånger snabbare än ML närmar sig. Våra resultat visar att vårt tillvägagångssätt kräver cirka 15% av den data som andra lösningar behöver: detta är ett betydande framsteg med avseende på den nuvarande teknikens ståndpunkt. Detta utgör en ytterligare fördel i form av kostnadsbesparingar för tekniska resurser, både vad gäller datalagring och programexekvering. Resultaten bevisar effektiviteten av förslaget, med 80% noggrannhet, cirka 10% lägre än genomsnittet för ML. Nyckelpunkten är skillnaden i tillvägagångssättet, som är värt att utvärdera avvägningen. Med tanke på den effektiva låga frekvensen av händelser som negativt påverkar prestandan och leder till eftersläpning, skulle det föreslagna tillvägagångssättet vara giltigt för vardagliga scenarier, men det skulle fortfarande vara tillrådligt att förlita sig på ännu mer exakt teknik under särskilt intensiva perioder.

Hinder för användning av scrum i ett programvarustartföretag / Barriers to scrum adoption in a software startup company

Qasim, Muhammad, Basutkar, Shreyas January 2022 (has links)
In the modern world, Scrum is widely adopted by many companies for software development, no matter the size of the company. As Scrum provides rapid development and meets the customer needs in a faster and efficient way, many companies want to move towards Scrum but moving towards Scrum is difficult and challenging due to different barriers for example cost, lack of experience, and so on. This thesis is to address the barriers which are involved during the Scrum adoption for software start-up companies such as communication, team mindset, backlog refining, daily stand up, and retrospective meetings. In this research report, these issues are divided based on the factors such as organization, people, process, and tools. We have figured out these barriers using action research based on the observation done during the Scrum team meetings and through interviews and surveys.

Exploring challenges faced by social workers on the management of foster care backlog at the Department of Social Development, Limpopo Province, South Africa

Matsoso, Sisimogang Philadelphia 11 October 2022 (has links)
Thesis (M.Dev. (Development Planning and Management)) -- University of Limpopo, 2022 / The foster care backlog has been a challenge in the National Department of Social Development for some years which resulted in the lapsing of foster care grants and thousands of children left without legal and statutory protection. Due to this, civil society took the Department of Social Development to court as this challenge impacted negatively on the family functioning of foster families as they lost access to social grants. The Department of Social Development was ordered by the South Gauteng High Court to come up with an extensive legal solution by the end of December 2014 but, to date, the foster care backlog is still piling up and foster families‟ standard of life is threatened. The social workers who are mandated by the Children‟s Act to conduct the statutory process and place children in foster care are inundated by the high foster care backlog. The aim of the research study was to explore the challenges social workers face in relation to managing foster care backlog cases at the Department of Social Development in the Polokwane Municipality area, Limpopo Province. The research study was based on a qualitative research method whereby a small sample of 21 foster care social workers from three service points (Aganang Cluster, Polokwane East and Polokwane West) were interviewed. The researcher used face to face semi-structured interviews to collect primary data from the participants. The findings from the study affirmed that there were indeed challenges in managing the foster care backlog. Lack of support and training, together with inequitable distribution of cases, are the most dominant challenges identified by the participants. In order for the provincial Department of Social Development to reduce the high caseload and for the clients to continue receiving the best service, the research study recommends that the vacant post be filled as soon as possible. Furthermore, training on legislation dealing with children including the Children‟s Act is also recommended for social workers. The researcher is of the opinion that the findings and the recommendations of the study may add value in managing foster care backlog in the Polokwane Municipality area and Limpopo Province as a whole, if they can be considered and applied.

Ngwenya, P. M. (Phindile M.) 01 1900 (has links)
The backlog in foster care applications has been an issue in the Department of Health and Social Development, Johannesburg office, for the last number of years, resulting in foster care placement applications accumulating and families’ quality of life being affected and compromised. The service providers are inundated with high caseloads. Foster care applications could take up to a year or longer before they are processed and finalised at the Children’s Court. The aim of the study was to explore and describe the factors contributing to the foster care backlog from the service providers’ perspective and to provide suggestions to address this continuing backlog. The researcher employed a qualitative research approach and an explorative, descriptive and contextual research design. Factors such as high caseloads, lack of resources and lack of support and training from management were identified as contributing to the backlog. Recommendations made are the immediate filling of vacant posts, induction of new social workers, provision of adequate resources and infrastructure as well as the division of foster care services. / Social Work / M.A. (Mental Health)

Low-cost housing in Witzenberg local municipality

Philander, Theresa-Anne 02 1900 (has links)
ABSTRACT The purpose of the study is to evaluate the housing process of Witzenberg Local Municipality and determine the involvement of the community and their perception regarding the whole process. The researcher is using a qualitative method to obtain the views, perspectives and feelings of the participants. For the purpose of the study is data collection limited to the sample population of people on the waiting list and those already in possession of low-cost house of the seven townships in the Witzenberg Local Municipality to. The researcher made use of questionnaires and interviews to collect data to make a profound finding and recommendation. In Witzenberg, 41% of households earn less than R30000 per annum (Witzenberg Local Municipality 2012: Online) which indicate that the Witzenberg Local Municipality has a high need for subsidized housing. The waiting list for low-cost housing in the Witzenberg Local Municipality currently stands at 6278 of which 1478 are a blocked housing project and a backlog of 4800 houses. The inhabitants of the Municipality received low-cost housing 8 years ago (Witzenberg Local Municipality 2012: Online). Witzenberg Local Municipality does has a housing problem, which stems from finance, affordability, insufficient land to erect housing projects, overcrowding, and quality of housing, staff shortage, unemployment, uncontrolled farm evictions and community involvement (Witzenberg Local Municipality 2007a:Online). Low-cost housing is in demand to address the challenges. Farm evictions, influx into the Witzenberg Local Municipality and forming of informal dwellings and increasing of squatter camps hold a serious threat to build sustainable, quality low-cost housing in the Witzenberg Local Municipality and with limit staff is in-flux control very hard to manage. Although the homeowners of the Witzenberg Local Municipality are happy to have received houses, they expressed much concern about the poor construction work, overall quality of the materials used as well as the housing process adopted by the Witzenberg Local Municipality. / Public Administration / M.

A Stochastic Analysis Framework for Real-Time Systems under Preemptive Priority-Driven Scheduling

Azhar, Muhammad January 2011 (has links)
This thesis work describes how to apply the stochastic analysis framework, presented in [1] for general priority-driven periodic real-time systems. The proposed framework is applicable to compute the response time distribution, the worst-case response time, and the deadline miss probability of the task under analysis in the fixed-priority driven scheduling system. To be specific, we modeled the task execution time by using the beta distribution. Moreover, we have evaluated the existing stochastic framework on a wide range of periodic systems with the help of defined evaluation parameters. In addition we have refined the notations used in system model and also developed new mathematics in order to facilitate the understanding with the concept. We have also introduced new concepts to obtain and validate the exact probabilistic task response time distribution.    Another contribution of this thesis is that we have extended the existing system model in order to deal with stochastic release time of a job. Moreover, a new algorithm is developed and validated using our extended framework where the stochastic dependencies exist due to stochastic release time patterns. / This is Second Version of the report.

Comparative implementation strategies for the progressive realisation of the right to adequate housing in South Africa, Canada and India

Mmusinyane, Boitumelo Obert 09 February 2016 (has links)
The central hypothesis of this thesis is that the universal fundamental right to adequate housing must be equally enforced by all states irrespective of its non-entrenchment as a constitutional, legislative and/or policy entitlement. Despite being a minority, poor Canadians still face the same sordid living conditions that the majority are experiencing in South Africa and India. If a developed country such as Canada, despite its available resources and housing policies, and, similar to South Africa and India as third world countries, fails to improve the poor’s standard of living, the right to adequate housing will remain a distant dream for many. Any housing implementation strategy must be able to reduce housing backlogs, eradicate homelessness and slums and in general improve the poor’s standard of living. The thesis considers the diverse implementation strategies of the right to adequate housing as adopted by South Africa, Canada and India and reveals how each country has experienced systemic challenges. Against the background of international and regional human rights obligations, key issues are investigated to determine how to properly implement, enforce and monitor the right, include the role of a constitutionally entrenched right, the adoption of a housing legislative and/or policy measures, the role of the judiciary, (in)action on the part of government and the part played by national human rights commissions. While each of these three countries approaches the issue in their own unique way, and each country makes its own contribution, what is required is a coordinated and multi-faceted housing implementation system. Although the point of departure was to determine what South Africa could learn from Canada and India, the conclusion is that both Canada and India can draw inspiration from South Africa. Nevertheless, the main conclusions are that South Africa must urgently conduct a comprehensive review of its regressive 20 year housing implementation strategy and India’s 61 years five year plans. The Canadian judiciary should be looking at ways to enforce the right within the Canadian Charter as well as its domestic legislation to include ‘social condition’ as a discrimination ground. While both Canada and India must review their housing policies their judiciaries should be evaluating the history of homelessness and the reasonableness of their adopted housing policies. / Private Law / LLD
