Abstract

Dynamic development of scheduling systems allows significantly improving currently realized tasks. Critical Chain Project Management (CCPM) is one of the methods of project management basing on network planning. In this method is utilized the concept of a critical chain derived from the Theory of Constraints. This method allows avoiding losses considered project time and resources. It results in quicker project implementation (20-30%), and in reducing the risk level considered with tasks realization. The projects are cheaper, and the risk of cost overruns is significantly reduced. Factors that distinguish CCPM method from traditional network planning methods are: the balance of resources and the introduction of buffers. Moreover in the CCPM method key elements are: times of tasks that are reduced from traditional estimates to realistic ones. Activities associated with the task start as late as possible in accordance with the ALAP principle (As Late As Possible). This work presents the process of managing the assembly of a shearer machine taking into account the process of safety buffers utilization and the whole project optimization. It is presented the estimation of buffers capacity to obtain the improvement of project realization task.

Highlights

  • Critical Chain Project Management (CCPM) method is one of the network methods for planning, executing and managing projects in single and multi-project environments

  • The buffer sizes and durations of tasks were estimated on the basis of statistical analysis

  • Statistical analysis concerning forecasting the parameters for describing the distribution of time availability and unavailability of these resources for the planning period showed that it is possible to reduce the total time of analyzed task by 75 days

Summary

Introduction

Critical Chain Project Management (CCPM) method is one of the network methods for planning, executing and managing projects in single and multi-project environments. Each project should be scheduled to achieve its objectives, taking into consideration these limitations For this reason, it is important to appropriate manage the project already in its first phase, that means in the planning phase. In many cases, the used project management system leads to the fact that the projects are not realized on time, with the ever increasing costs [1, 2]. This is why new approaches to project management are under consideration. Time of a given task realization should be appropriately chosen taking into account the factor of uncertainty in the given project management. It is possible to specify the spare time (safety buffers) [3 - 5]
