the task of balancing of assembly lines is well-known in mass production system but this problem is np-hard even for the simple straight line. therefore, utilizing heuristic methods for these problems is totally unquestionable. furthermore, in line with balancing problems, heuristic methods are the foundation of the metaheuristic methods, thus it seems to be necessary to use more efficient heur...

In this paper Algorithm is presented to perform critical path method in a fuzzy environment. The trapezoidal fuzzy number given by decision makers or characterized by historical data are utilized to assess the activity time in a project network. The fuzzy shortest path problem thus obtained is compared with conventional method.

The Critical Path Method (CPM) is useful for planning and control of complex projects. The CPM identifies the critical activities in the critical path of an activity network. The successful implementation of CPM requires the availability of clear determined time duration for each activity. However, in practical situations this requirement is usually hard to fulfil since many of activities will ...

Several protocols have been proposed to synchronize the logical processes (LP’s) of a parallel discrete event simulation (PDES). While most protocols have been known to perform well under certain conditions, the general observation has been that the performance of protocols is sensitive to the application being simulated, sometimes even to a particular instance of it. In this technical note, we...

To cut down cost in a competitive environment, airlines must avoid delays and operation inefficiencies in both airside and landside. However, previous studies have paid little attention to an airlines’ ground operation in airports’ cargo terminals. The purpose of this paper is to demonstrate how to employ the Fuzzy Critical Path method (CPM) to find out airport’s ground critical operation proce...

This paper presents the design, implementation and testing of the critical path analysis technique on the IPS performance measurement tool for parallel and distributed programs. We create a precedence graph of a program’s activities (Program Activity Graph) with the data collected during the execution of a program. The critical path, the longest path in the program activity graph, represents th...

T In this paper, we propose an approach based on hardware-software partitioning to minimize logic area of a SOPC circuit "System on a Programmable Chip". This approach minimizes the SOPC area while satisfying a time constraint. To minimize this area, we propose an algorithm to determine the critical path with the largest number of hardware tasks in a given data flow graph. Once these hardware t...
