Most inventory researches assume that the production level can be fluctuated arbitrarily. However, in many firms, large fluctuation in production levels may be very costly. This paper addresses the coordinated pricing and inventory control problem in a smoothing production system, in which the production level is constrained between a maximum and a minimum level in each period and the price can...

Polca is a material control system that focuses on shop floor throughput time control in production situations with high variety and customization. It uses an authorization mechanism that consists of route-specific capacity signals (polca cards) and product-specific release signals (ERP system). The route-specific capacity signals level the maximum amount of work in progress within a loop. Each...

In flexible manufacturing environments, the performance of a production system is often affected by the sequence of operation. While performance evaluation, improvement and lean design of production system have been studied extensively, the joint effect of productivity and quality parameters on operation sequencing remains practically unexplored. Indeed, determining the optimal operation sequen...

During the coking process in coal chemical industry, the stability of gas collector pressure is an important guarantee for the normal production of coke oven. This paper combines the adaptive fuzzy control algorithm and the fuzzy decoupling rule to control the gas collector pressure, and coordinates the entire system through the establishment of pre-header suction supervisory control. The speci...

OVERVIEW: There is a growing demand for renewable energy resources with the rise of concern for the environment. Many fear that the increasing distributed energy resources will degrade the power quality of the distribution systems. While microgrids can reduce the amount of degradation, they can also operate almost completely independently, thus complicating the balancing of supply and demand co...

We propose an MAC centric cross-layer approach to address the problem of multimedia transmission over cognitive Ultra Wideband (C-UWB) networks. Several fundamental design issues, which are related to application (APP), medium access control (MAC), and physical (PHY) layer, are discussed. Although substantial research has been carried out in the PHY layer perspective of cognitive radio system, ...

This paper addresses the design and implementation of a multiagent based control architecture to support modular reconfigurable production systems. The requirements for plugability of modules (manufacturing components) and product changes were considered and tested against an educational platform based on fischertechnik, which resembles a production system composed of several workstations conne...

The Economic Production Quantity (EPQ) is one of the most applicable model in production and inventory control environments. Like other classical production and inventory control models, it is derived based upon assumptions that cause limited real-world applications. Continuous and constant-rate delivery of orders, infinite availability of warehouse spaces, and applicability on a single product...
