Adjusting replenishment orders to reflect learning in a material requirements planning environment
Article Abstract:
Material Requirements Planning (MRP) systems require mangers to calculate expected yield losses in order to manage release planning. Managers must plan orders to exceed needs in order that net yields meet actual requirements. Certain manufacturers, particularly in the field of high technology, initially have low yields that are improved steadily through experience. However, MRP literature reveals that yields are seldom systematically adjusted to improve yields. Substantial improvements in inventory levels can be realized for low yield manufacturing processes through the application of a single product, single stage MRP model that synthesizes learned behavior into conventional MRP formulations and affects an adjustment of replenishment orders.

The influence prism in SMEs: the power of CEOs' perceptions on technology policy and its organizational impacts
Article Abstract:
A model that relates CEO's environmental perceptions, strategic business orientation, scanning and structuring properties, technology policy, firm performance measures and realized innovative efforts of the firm is proposed. The model is used in the study of small manufacturing enterprises where the CEO is known to have a major role. Results provide valuable insights on technology and strategy in SMEs, even if minimal empirical evidence on the formulation or impact of technology policy in small firms is available. The influence of environmental perceptions of CEOs on the development and enactment of technology policy in SMEs and subsequent organizational effects in terms of realized innovative efforts and firm performance are also examined.

Inventory control in hybrid systems with remanufacturing
Article Abstract:
A study was conducted to investigate the areas of production planning and inventory control with remanufacturing. The study aimed to analyze the impact of remanufacturing in PUSH controlled production/inventory systems, where all returned products are remanufactured as early as possible, and in PULL controlled production/inventory systems, where all returned products are remanufactured as late as is convenient. One significant research finding is that efficient planning and control in these systems tends to be more complex than in traditional systems without remanufacturing. Factors partly responsible for these complexities include systems interaction and return uncertainties. These factors are not existent in traditional systems.
