Comparison for the Characteristics of the OA, MRP, and ERP Systems

Information systems play varied roles in businesses and in the growth of businesses as a result of advancements in computer technology. On the comparison of MRP and ERP and the development process, certain scholars have offered their perspectives. There are, however, few researches that compare the traits of OA, MRP, and ERP in detail. In this paper, the features of office automation systems, material demand planning systems, and manufacturing resource planning systems are contrasted and discussed along with their historical development, present state, and various system goals. This study provides a summary of the OA, MRP, and ERP systems. The three MRP development stages are outlined, along with the distinctions between the relevant environment, production process, capacity needs, fundamental parts of e-commerce activities, management modules, and other characteristics. Enterprise managers can effectively improve the office and production efficiency of enterprises by analyzing, designing, implementing, and combining management knowledge of different systems. These results shed light on guiding further exploration of understanding the comparison of three system characteristics.

A Development and Implementation of Manufacturing Resource Planning System for Small and Medium Enterprises

Material Requirements Planning (MRP) refers to a system of management practices where production planning is integrated with inventory control. According to this paper, we have been able to make significant progress toward a revised Manufacturing Resource Planning (MRP II) system. During the application of the MRP II database, it was also considered how much dataset might be obtained using reports. MRP II database creation in MS Access software is covered in steps 1 and step 2 of this research article. This paper refers to the MS Access software to create a database that incorporates the theoretical knowledge and suggested a custom MRP II solution. In this paper, a three-step technique as a research methodology to formulate and apply a customized MRP II model was used. For the creation of a custom MRP II system database, this paper employed the MS access application over other commercially known software. With MRP's core idea, we should be able to schedule just what materials are required and when. The relevant literature has also put significant emphasis on technical issues, e.g., the ineffectiveness of MRP frameworks for optimization of the internal workflow.

Investigation of the impact of applying TOC in MRP using a case study

In this research, the impact of applying TOC in MRP systems has been studied through a case study. First the theories of TOC and MRP and their integration histories have been reviewed. The research methodology was devised using library and field studies. The proposed method was applied to Tabriz Diecast Aluminum Casing and Bending Company. The company organizational documents have been used in studying the impact on company operations. The collected documents and information were thoroughly evaluated and analyzed to obtain the final results of using TOC in production systems and MRP as presented in this paper. In today’s economy, cost reduction and increasing production output and quality are regarded as top priorities for survival and competition as they can guarantee the success of a company in the long run. Key words: Constraint, theory of constraints, manufacturing resource planning OR, manufacturing resource planning (MRP), optimized production techniques (OPT).

Prediction of manufacturing resource requirements from customer demands in mass-customisation production

Mass-customisation production is a new manufacturing approach to produce customised products based on requirements of individual customers while maintaining the quality and efficiency of mass production. Due to the large variations of customised products, the traditional methods for planning manufacturing resources based on volumes of mass produced products are not effective for mass-customization production. In this research, a new manufacturing resource planning method is developed by studying the relations between customer demands and manufacturing resource requirements based on the true data from a mass-customisation production company—Gienow Windows and Doors. In this research, first the relations between the customer demands, modeled by sales data at levels of whole company, sales branches, and markets in sales branches, and the manufacturing resource requirements, modeled by labour requirements of different production lines are studied. Fuzzy pattern clustering method is employed for classifying the resource requirements into patterns to further understand the relations. Based on this study, linear regression and neural network are used to model the linear and non-linear relations between customer demands and manufacturing resource requirements, and to predict the manufacturing resource requirements from available customer demands. A manufacturing resource planning system was developed to demonstrate the effectiveness of this introduced approach.

Petri net-based workflow modeling for a die and mould manufacturing resource planning system

This paper presents a modeling method of hierarchy-colored and timed Petri net (HCTPN) that has an agent place. A workflow model for the die and mould MRP II system is established and the validity of workflow model is analyzed via the HCTPN. Combined with the control logics, the HCTPN-based model can accurately express the MRP II running process, so it is also the base of emulation and operation of the MRP II.

A new framework for MRP systems to be effective in engineered-to-order environments

Present day manufacturing resource planning (MRP) systems do not perform well in engineered-to-order (ETO) environments. A study of the use of MRP systems by ETO companies has led to the development of a new framework for manufacturing planning systems. New features allow better coordination of activities in the areas of engineering, material acquisition, production, and delivery. The new framework especially addresses the problem of planning with uncertain information which is characteristic of an ETO environment.

An Approach for Developing Flexible MRP Systems

Like most software systems, manufacturing resource planning systems suffer from high maintenance expense. This article examines how object-oriented techniques can be used to develop systems that require less maintenance. Emphasis is placed on reuse to lower postdevelopment costs.

Critical success factors in implementing MRP and government assistance: A Singapore context

It is generally acknowledged that Manufacturing Resource Planning (MRP) could revolutionize manufacturing operations. Making use of data from a recent survey of MRP practices in Singapore conducted jointly by the National Computer Board (NCB) and the National University of Singapore (NUS), this paper provides a profile of manufacturing companies in Singapore that both have and have not implemented MRP. The Critical Success Factors involved in implementing MRP are identified and the theoretical justification behind each factor examined. Finally, the ways in which the Singapore Government can help local companies implement, operate, and maintain MRP systems are discussed. It is an expensive investment, and difficult to implement, due to its complexity. It is hoped that knowledge and understanding of these factors will assist firms in successfully implementing MRP and enable them to further improve their systems in order to maximize returns.

Manufacturing resource planning systems (MRP) case study: Feature selection system (FSS) for microcomputer users and manufacturers

The selection of appropriate features for inclusion in microcomputer systems can be very frustrating for both hardware and software manufacturers, as well as for end-users. This study describes an interactive microcomputer based feature selection system (FSS). The feature price contribution margin (FPCM) measures to what degree a specific feature meets end-user needs. FSS produces a segmented income statement of possible future products lines. It also compares the outcome of integrating and bundling a feature into a product vs marketing this feature as a separated “add-on” product line.

Health care requirements planning: A conceptual framework

A clearly defined closed-loop operations management system comparable to the Manufacturing Resource Planning System (MRP-II) does not exist in the health care industry. Therefore, a study was conducted to evaluate the basic modules of MRP-II in terms of their applicability for developing a workable health care requirements planning system.

Safety Stocks in MRP—Systems with Emergency Setups for Components

Material Requirements Planning or Manufacturing Resource Planning (MRP) systems originally were designed for a deterministic environment. Often, however, demand for finished products is uncertain and some type of buffering mechanism is necessary to provide desired levels of service. When the schedule is replanned each period, as typically is done, variability of demand may manifest itself in the form of early or “emergency” production runs. Safety stock may serve to avert some or most of these emergency production runs. We have developed a heuristic algorithm which is shown to provide extremely good guidelines for setting safety stock levels.

Problems are classified as being management, technical, and behavioral. Recommendations are provided for each type of problem based on an extensive review of the literature. A discussion is provided of current trends in the manufacturing information system field.

Manufacturing resource planning: an integrated decision-support system

A manufacturing resource planning system provides a vertically and horizontally integrated set of plans for each level of management and for each of the supporting areas of the organization. Computer simulations are used to generate these coordinated plans. Thus, a total system model is available for simulating alternative actions and evaluating the effects of each strategy of the business enterprise. The input requirements, benefits, and problems associated with such a planning and control system are also discussed.
