Emanfactoning & optimized planning
(Al-Neelain University, 2002) خلود محمد جميل ابومارية
Abstract This thesis deals with one ofthe most importing manufacturing model which is material requirements planning. It is a form of backward scheduling. MRP is an information management system that ensures that material is not ordered for production until there exists an end item for it to produce: MRP starts with the ﬁnished product and works backward to plan the requirements ofall necessary raw materials using BOM issue. The major idea of MRP is to keep stock value to minimum. MRP is applicable to discrete and dependent demand systems, allocating items in inventory when they are required. The system must be time phased so that predetermined materials arrive at the point in time when they are needed. Time phasing results in reduced inventory levels, since holding costs are a factor in detennining ordered raw material or work-in-progress (WlP). Thesis aims to realize an integrated system that has rapid response to changing requirements and capability to integrate heterogeneous manufacturing activities. At first, the application accepts the customer’s order (through Sales Eng.) and performs material requirement planning process, which results is material scheduling and deliveries date. Then MRP monitor daily planned order to production model that carries out real-time scheduling and production. At the same time, MRP sends order to supplier for purchasing raw materials (shortage). After completing production task, production model returns the relevant infomiation about finished parts. Once the customers add or modify orders, MRP system will update data automatically to respond to the changes ofcustomer requirements rapidly. The smart draw tools are applied for analyzing and designing phase while total I application in which MRP system uses visual F0xPro version 6 as an implementation language. Kevwordsz MRP.

Abstract The main idea of this thesis is based on a simulation for groundwater demand & consumption system. The study ofthis system needs as usual a heavy investigation effort and takes long time by using traditional methods to analyze the‘ rates ofwater consumption and the rate of water demand. For such studies we need information to determine the water quantities that fulﬁll the water needs of Khartoum population for the coming twenty years according to the population increase. This thesis contains information about water consumption and population increase in Khartoum state; it focuses on the problems caused by lack of water in Khartoum state. We have illustrated the various simulation models mentioning the related deﬁnitions and taxonomy. Also we have illustrated various techniques for estimating future consumption and the prediction of future population. This thesis is composed of all the steps and procedures that have been taken within the simulation, starting from the beginning of the simulation up to the simulation results. Finally we found that the existing groundwater with the recharge from the Nile which was estimated to be about 100 million cubic meters per year can not sufﬁce the population demand for water for the coming years in Khartoum state. All one after 25 years from the simulation beginning year the Khartoum population demand for water reach 866329415 milliard cubic meter in the year where this quantity of demand exceed the groundwater total capacity which was estimated to be about 85 milliard cumc meter plus the recharge from the Nile which was estimated to be about l00 million cubic of meter pear a year.

Enhanced model for Usability Requirements D 7 Elicitation
(AL-Neelain University, 2015) Elsiddig Khogly Elsiddig Khogly
Introduction: Usability is one of the most important aspects of requirement engineering .The HCI community has developed guidelines and recommendations for improving the usability system that are usually applied at the last stages of the soﬁware development process. On the other hand, the software engineering community has developed methods to elicit functional requirements in the early stages, but usability has been relegated to the last stages together with other non- functional requirements. Therefore. there are no methods of usability requirements elicitation to develop software within both communities. This thesis details a framework that looks at how to deal with certain usability features in the early software development stages. A Model contains ﬁve steps that should be achieved in order to elicit the usability requirement as the non-functional requirement. A case study has been conduct to test and evaluate the proposed method. Results indicate that such model will aids to increase the developer's awareness toward usability and there for better usability feature and higher user satisfaction could be accomplished. Methods: A survey study (Questionnaire and interview) has been used to study and investigate a particular community (Developers) also SPSS version 2] has been used to analyze the data of the Questionnaire. Results: this result was reached by the survey study and found that (88.4%) of the sample under study (Developers) haven’t any speciﬁc guidelines to deal with NFRs and especially usability. The evaluation was conducted to the proposed model is testament to how important guidelines of usability and the difference is clear and visual between the system in the first level and the second level. The proposed an approach for elicitation process helped to elicit usability requirements and less time consuming way to identify usability functionality. Discussion: There are some limitations related to Requirements Engineering knowledge spicily the requirement type and method to elicit it and Human-Computer Interaction (HCI). Also Companies that develop software system and developer have less method to elicit usability requirement as non-functional requirement and there is no speciﬁc guidelines to deal with non-functional requirements especially usability requirements.
Hybrid Agile Method for Sudanese Companies
(AL-Neelain University, 2016) Amal Abdalla Elshaﬁe MohamedElnour
Agile software development refers to a development methodology that uses iterative development, frequent consultation with the customer, small and frequent releases. Some organizations adopt agile practices to become more competitive, improve processes, and reduce costs. Other organimtions are skeptical about the beneﬁts of agile development. Despite the importance of agile software development and beneﬁts of it in reduce the cost, increase the quality, respond to change and complete the project in time. Sudanese companies and organizations avoid using in the Agile development process because of the different culture and work environment in the Sudanese companies. To know the use of agile development and determine problems and fears face the developer this study used questionnaire to identify what methodologies soﬂware practitioners in govemmental and commercial organizations to develop soﬁware for different sizes of projects. lnfomiation regarding their opinions on agile methodology (methods, problems and best practice) From the results of the questionnaire this research proposed a new method of agile development combines Scrum, XP and Kanban to take the beneﬁts of each method and solving their problems and limitations, ﬁmhermore, the proposed method take advantage of the scrum in management practices, XP in engineering practices and kanban in workﬂow management practices. Also through the questionnaire study to reach some of problems experienced by the participants, the problem was solved by Enhancement on the proposed method. One of these problems is low documentation that have been solved through adding new documents to increase documentation without adding more complexity of the project. Also the problem of the low planning for the project has been solved by adding kickoff meeting to be a full planning of all project. Finally the issue of customer collaboration all of the time was solved by adding a new individual to team is business analyst who can take the customer's place in the event of unavailability. ' The new agile method implemented the concept of agile development and all the principles in line with the culture of Sudanese companies to solve the problems, take advantage of all the features and beneﬁts of agile development including reduce development time, reduce the cost of production, increase the quality of software and customer satisfaction.
Develop Methodology for Bioinformatics Software Development Using Agile
(Neelain University, 2017) Aayat Omer Idrees Abdelmutaleb
Abstract Agile is an iterative approach to software development that relies on strong collaboration and automation to keep pace with dynamic environments. It provides a model for collaboration between software engineers and researchers. There is a huge gap between the software engineer who work as a bioinfomiatician and the bio science researcher in collaborating in developing computational and bioinformatics tools and databases. Agile methodologies represent one of the most common and widely used software development and management due to its simplicity. Because of lack of scientiﬁc knowledge and practice in each ﬁeld about the other ﬁeld. The development of a system in the ﬁeld of bio-informatics requires full cooperation between specialists in the ﬁeld of biology and specialists in the ﬁeld of computer and work together as a team. In this research, we propose a framework that can be used in the research environment using Scrum as an agile method, we have successfully used agile development approaches to create and maintain biomedical software, including software for bioinformatics. We integrated the SCRUM and EXTREM PROGRAMMING ‘PAIR PROGRRAMING’ methodologies, which we found to be a successful selection and simple solution, efﬁcient, inexpensive, applicable, and positively affect the development process. . This new method should be wide spread among the bioinformatics and computational biology research group to get their feedback and enhancements suggestions. The new tools should be developed according to this method to enable the research team to use this method more efﬁciently.
