this paper is a research on the ordering planning of a supply chain with one supplier, multi buyer and multi deteriorating items. items have fixed life time and expire dates. the ordering period is taken as variable and must be computed the proposed models. the problem is studied via two different approaches the first is the joint replenishment, based on the hwang and chew's model [3] and ...

The use of Enterprise Resource Planning system in manufacturing companies aims to increase the companies’ productivity. In this case, an integrated ERP could maximize production. Thus, researcher conducted a study that discussed application Odoo V12.0 chicken company. This research focused on inventory sectors. There is no special manage section. business process reengineering has been done wer...

The primary objective of this paper is to study the impact of selected inventory parameters and management techniques on the performance of an expanded and comprehensive retail supply chain. Speci"cally, we study the sensitivity of supply chain performance to three inventory planning parameters: (i) the forecast error, (ii) the mode of communication between echelons, and (iii) the planning freq...

In equipment-intensive industries such as truck, electronics, aircraft and dredging vessel manufacturing, service parts are often slow moving items for which the transshipment time is not negligible. However, this aspect is hardly considered in the existing service logistics literature. In this paper, we consider this aspect and propose a customer-oriented service measure which takes into accou...

This paper presented an application of Fuzzy mathematical programming model to solve network design problems for supply chains via considering aggregate production planning (APP). APP goals to minimize all costs through optimal levels of production, subcontracting, inventory, backorder and work levels over a time period to meet the demand. Fuzzy logic was applied to solve the uncertain producti...

This research work develops a decision support model for a network design problem concerning a spare parts closed loop supply chain. It involves the formulation of an optimization model that takes on a mid to long-term planning perspective and covers decisions that have lasting and binding impact on organizational performance. These decisions include investment, location assignment, and invento...

It is almost unquestionably accepted by most observers that inventory ratios decreased over time. There are so many Enterprise Resource Planning systems implemented and so many just-in-time ideas successfully introduced in companies that we almost automatically conclude that inventories went down. However, as will be shown in this study, this conclusion is somewhat hasty. Since most inventory r...
