a three stage production system is considered in this paper. there are two stages to fabricate and ready the parts and an assembly stage to assembly the parts and complete the products in this system. suppose that a number of products of different kinds are ordered. each product is assembled with a set of several parts. at first the parts are produced in the first stage with parallel machines a...

Switched Ethernet has many features for real-time communications but cannot guarantee the timely delivery of a real-time message due to possible collisions on the output ports. This paper first suggests a feasible condition for real-time communication of periodic messages on a master-slave-based synchronized switched Ethernet. Then an EDF (Earliest Deadline First)-based scheduling algorithm tha...

Heterogeneous Distributed Computing (HDC) system consists of Workstations (WSs) and Personal Computers (PCs). In HDC system, each WS/PC may have different processor and performance. In order to take advantage of this diversity of processing power of a system, an effective task partitioning, scheduling, and load balancing are needed to get the optimum performance. This paper examines the effecti...

In a series of papers, Küsters et al. investigated the relationships between various notions of simulation-based security. Two main factors, the placement of a “master process” and the existence of “forwarder processes”, were found to affect the relationship between different definitions. In this extended abstract, we add a new dimension to the analysis of simulation-based security, namely, the...

Production management is a set of decisions that must reflect a compromise between customers’ satisfaction and production criteria such as cost, delay and quality. The goal of production management is to ensure the continued success of the firm. Industrial planning plays a central part in this one. The latter can be divided into three hierarchical decisional levels: the strategic level deals wi...

PvmJobs is a general bag-of-jobs library for PVM that works with any user created job structure in a master/slave paradigm. A master can spawn slave processes, schedule and dispatch jobs to slaves, coordinate and synchronize the activities. A slave process obtains a job from the master, performs a set of prescribed tasks, returns results to the master, and obtains the next job. Slaves are organ...

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...

Supply chain planning in manufacturing companies is approached in this paper through empirical case-study research. The target was to chart how different types of manufacturing companies are specifying their future volumes and to identify the type of collaborative planning they are implementing with customers and suppliers. Based on interview study results, a framework is presented to explain h...
