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.

project planning is part of project management, which is relates to the use of schedules such as gantt charts to plan and subsequently report progress within the project environment. initially, the project scope is defined and the appropriate methods for completing the project are determined. in this paper a new approach for the critical path analyzing a project network with random fuzzy activi...

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...

In Wireless Sensor Networks, data collection by the Mobile Sink (MS) from the sensor nodes is a challenging task. In the proposed approach, the MS visits an optimal set of subsinks in order to collect data instead of visiting all the nodes in the network. In this paper, the subsink selection has been proven to be optimal since the subsinks are chosen by the Critical Path Method (CPM). Initially...
