This highly informative, practical book shows you how CPM: There are six dummy activities viz. Dummy activities are fictitious activities as these activities do not need any resources.
Dummy activity performs two functions: - I. Maintain the correct relation of precedence of activities II. Make network diagram with rule that no two or more activities can have same starting and completion nodes. A diagram is built up by sections. Within each section the task is accomplished one arrow at a time by asking and answering the following questions for each job: 1 What immediately precedes this job?
By continually back-checking, the chance of making omissions is small. The individual sections then are connected to form the complete project diagram. In this way, projects involving up to jobs have been handled with relative ease.
From a scientific viewpoint, the idea of diagramming the technological relations among the jobs in a project is almost trivial. Such diagrams are used in many engineering and mathematical applications. However, diagramming is an innovation in project work which has given planners several benefits: 1 It provides a disciplined basis for planning a project.
On the basis of estimated elapsed times, we may compute approximations to the earliest and latest start and completion times for each job in a project. This information is important not only for putting a schedule on the calendar, but also for establishing rigorous limits to guide operating personnel.
In effect, it tells those responsible for a job when to start worrying about a slippage and to report this fact to those responsible for the progress of the project.
In turn, when this information is combined with knowledge of the project's topological structure, higher management can determine when and how to revise the schedule and who will be affected by the change. This kind of information is not determined accurately by traditional methods.
What this information provides is the basis for a system of management by exception. A non-computer approach to the critical path method The critical path method CPM for planning, scheduling, and control of project operations is a new and useful tool now becoming available to the industries having repetitive work e. Successful applications of this method have already proven its value. Critical path method can be used through the use of computer or without the help of computer.
To date, except for the simplest of cases, the use of this technique has been largely dependent on programmed solutions by electronic computers. This report presents the mechanics of non-computer methods for applying the critical path method. These employ the same input data and furnish the same output information as the computer methods. In addition, alternate approaches to solution of the problem are presented which permit the important scheduling variation phase to begin with a normal estimate rather than a set of data for an artificial condition.
This is the main advantage of non-computer approach of applying the critical path method. There are three main advantages of non-computer approach of critical path method: - a The non-computer method is helpful for obtaining the benefits of critical path scheduling that is practical to apply to many of the projects encountered by the various organizations.
The solutions of a complex problem by computer methods eliminate tedious calculations and possible errors. It is a valuable step forward. This paper is not intended to oppose such methods, but, rather, to offer a stepping stone between conventional procedures and these more sophisticated practices.
First, many potential users find it inconvenient to use electronic computers or are not yet "computer conscious.
It is anticipated that a broader acquaintance with, and use of, the critical path method, made possible by non-computer methods, will lead eventually to an even wider employment of computer techniques as well as the development of improvements in them. All types of construction and maintenance work. Retooling programs for high volume production. Budget planning. Mobilization, strategic and tactical planning. Low volume production scheduling. Installation, programming and debugging of computer systems.
Assembly and testing of electronics system. All these applications are suggestive only. This list is almost endless as critical path method can be used for all repetitive application where the time required for carrying the various activities can be calculated.
CPM is deterministic model of project management that is used for the repetitive projects. Critical path method can be used for number of field of operation management e.
Dummy activities are used to maintain precedence and fulfill the rule that no two or more activities can have same starting and completion nodes. There are two types of times for every activity i. Normal time is always greater than crash time for an activity. To complete an activity in less time, it requires more resources and correspondingly the cost of carrying out the activity increases.
Critical path method can be used with the help of computer as well as without the help of computer. Computer is used for complex problems only as there are many advantages of manual approach e.
Critical path method CPM is used for repetitive project for which time required to complete the various activities can be found or known. Please enter your comment! Please enter your name here. You have entered an incorrect email address!
