The Critical Path Method (CPM) and its development to probabilistic environment, the Program Evaluation and Review Technique (PERT), are the most common tools for predicting and managing different short time or long time projects. However, one of the main difficulties in using mathematical models in real world applications is the vagueness and uncertainty of data and parameters such as activity...

Modern processors come close to executing as fast as true dependencies allow. The particular dependencies that constrain execution speed constitute the critical path of execution. To optimize the performance of the processor, we either have to reduce the critical path or execute it more efficiently. In both cases, it can be done more effectively if we know the actual path. This paper describes ...

Executive Summary The importance of proper management of projects has not gone unrecognized in industry and academia. Consequently, tools like the Critical Path Method (CPM) and the Program Evaluation Review Technique (PERT) for project planning have been the focus of attention of both practitioners and researchers. Determination of the T ime to C omplete the J ob (TCJ) in PERT networks is impo...

In this paper we consider the so-called type-I assembly line balancing problem (ALBP-I), in which the objective is to minimize the number of workstations needed for a given cycle time. ALBP-I is one of the well-known NP-hard problems in operations management, and many optimal approaches (including 0-1 integer programming model, branch and bound algorithm, dynamic programming model, etc.) have b...

project scheduling inevitably involves uncertainty. The basic inputs (i.e., time, cost, and resources for each activity) are not deterministic and are affected by various sources of uncertainty. Moreover, there is a causal relationship between these uncertainty sources and project parameters; this causality is not modeled in current state-of-the-art project planning techniques {such as simulati...

As the complexity in construction projects increased, simply managing the obtained float values and critical path(s) by the CPM method usually results in more difficult schedule control and, consequently, in incorrect decision making due to non-realistic float values. This study thoroughly reviewed various float types in the literature and professional project management systems, and discussed ...

In this paper critical path analysis is used for predicting the behavior of conservative cellular network simulation on a distributed simulation environment. Parallel event traces, i.e. event traces that contain both real and null messages, are used for the analysis. A receive-process-send approach is proposed for computing the event execution times required by the critical path analysis. A pro...

In this paper, a new very fast fault simulation method to handle the X-fault model is proposed. The method is based on a two-phase procedure. In the first phase, a parallel exact critical path fault tracing is used to determine all the detected stuck-at faults in the circuit, and in the second phase a postprocess is launched which will determine the detectability of X-faults. Keywords-digital c...

The purpose of this study was tc identify the relationship between reading Lchievemert and a set of social and individual variables through the use of a critical path analysis. Data, taken from Cycle II of the Naticnal Health Examination Survey, included statistics on a national sample of 7,119 children, ages six through eleven years. Four variables were included in this study: sex, race, age, ...
