Critical Path method (CPM) is widely used in project scheduling and controlling. In conventional project scheduling problem, the crisp numbers are used for the activity times. But in reality, in an imprecise and uncertain environment, it is an unrealistic assumption. To represent the uncertainty involved we have considered the interval-valued numbers to represent the activity times. In this pap...

This paper challenges the conventional thinking, by proposing a new way to understand and use the term critical-path. At stake is much more than a semantic discussion of terminology. Numerous surveys have confirmed that CPM schedules are used for two primary reasons: project management and dispute resolution. To support either use, the critical-path must be identifiable in a consistent, objecti...

Indonesia is currently actively developing infrastructure to improve the economy and welfare of itspeople. One developments undertaken by government road pavement. CV.X company that won asphalt project tender with a contract value IDR 4.046.873.346 must complete it within 114 days. During process working on project, there were indications possible delays in completion. So this study aims perfor...

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...

The Critical Path Method (CPM) and the Repetitive Scheduling Method (RSM) are the most often used tools for the planning, scheduling and control Linear Repetitive Projects (LRPs). CPM focuses mostly on project’s duration and critical activities, while RSM focuses on resource continuity. In this paper we present a linear programming approach to address the multi objective nature of decisions con...

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.

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...
