a r t i c l e i n f o The planning and subsequent implementation of Enterprise Resource Planning (ERP) systems still present a significant challenge for most organizations. Although consulting firms and customer enterprises have been aquiring more experience and expertise in the field, the level of sophistication of these systems and their wide organizational and social impact frequently leads ...

In a multi-item inventory system, such as an assemble-to-order manufacturing system or an online-retailing system, a customer order typically consists of several different items in different amounts. The average order-based backorders are the average number of customer orders that are not yet completely filled. While this is an important measure of customer satisfaction, it has not been widely ...

a comprehensive and integrated study of any supply chain (sc) environment is a vital requirement that can create various advantages for the sc owners. this consideration causes productive managing of the sc through its whole wide components from upstream suppliers to downstream retailers and customers.  on this issue, despite many valuable studies reported in the current literature, considerabl...

Two variants of a simple stochastic model for planning the inventory of spare components supporting maintenance of an industrial system are developed. In both variants, the aim is to determine how many spare components are needed at the beginning of a planning interval to fulfil demand for corrective replacements during this interval. Under the first variant, the acceptable probability of spare...

This report is an e ort to consolidate two di erent avors of a surplus inventory matching problem encountered in the steel industry: Surplus Un nished Inventory Matching, and Surplus Finished Inventory Matching. This report is compiled from two other reports that describe the heuristic solution approaches developed for a real world application of these problems [1, 2]. The focus here is to moti...

In the process industry, plant production is completely halted every so many years for large-scale maintenance comprising inspection, repair and overhaul. It paramount that this shutdown completed according to planning, which requires timely availability of replacement parts. setting, we present a spare parts optimization model algorithm includes cost-time trade-off precedence constraints betwe...

This paper examines the assertion that partial pooling of customers is sometimes favored over complete pooling on the sole basis of demand correlation. First, the management of inventory within a supply chain is discussed, with speci2c attention paid to risk-pooling. Then, the claim that partial pooling can dominate is theoretically discussed. The conditions under which previous research found ...
