In manufacturing, the interaction between the design of a product and the process to manufacture this product is studied in detail. Consider, for example, material requirements planning (MRP) as part of current enterprise resource planning (ERP) systems, which is mainly driven by the bill of material (BOM). For informationintensive products such as insurances, and many other services, the workf...

Material control schemes can be classified as push, pull, or hybrid strategies. This paper compares the performance of MRP (push) and kanban (pull) for a multi-stage, multiproduct manufacturing system. Using simulation experiments we analyze system performance under different product mixes and observe that in certain environments with advance demand information kanban-based pull strategies can ...

Enterprise Resource Planning (ERP) packages have, in the last five years, transformed the way organisations go about the process of providing Information Systems. Instead of crafting each new Information System locally, organisations are able to install well-integrated, internationally sourced packages which seek to incorporate best practice from IT systems world-wide. These packages also provi...

While there has been considerable work over the years on multistage lot-sizing models, particularly in an MRP environment, there has been relatively little work on systems recognizing the WIP effects when there is gradual conversion of the components into the final product, as in production planning using the EPQ model for planning the final product. Here we consider lot-sizing planning for a t...

lean manufacturing is a systematic approach to identifying and eliminating wastes (non-value added activities) through continuous improvement by conveying the product at the pull of the customer in pursuit of production. in a more basic term, more value with less work. since lean manufacturing eliminates many of the problems associated with poor production scheduling and line balancing, lean ma...

Safety stock and safety time are two well-known buffering solutions of material requirements planning (MRP) processes to mitigate against supply demand uncertainty. While the significance proper inventory in managing change has been extensively researched, chain management research on period gotten less attention. Earlier operations quantitative studies, particular, have often evaluated utiliza...

Emergency response fleets often have to simultaneously perform two types of tasks: (1) urgent tasks requiring immediate action, and (2) non-urgent preventive maintenance that can be scheduled upfront. In Huizing et al. (2020), proposed the Median Routing Problem (MRP) optimally schedule agents a given set tasks, such time for remains minimal. They both an exact MILP-solution fast, scalable accu...

Supply chain management (SCM) is critical to the success of manufacturing industries. Advanced production planning and scheduling functions capable coping with activities in a supply (SC) are presently needed. A finite capacity material requirement (FCMRP) system for three-stage SC, defined as “3-SC FCMRP,” presented herein. The aims generate feasible transportation schedules SC based on manufa...
