Abstract
The theory of pro ject planning and control by network planning techniques has undergone serious scruting and considerable expansion since the early models of CPM and PERT were advanced in 1959<Furthermore, the scope of interest, and the power of analysis of such theory have expanded well beyond the originally envisaged temporal considerations to include many more topics, such as the study of the optimal project (’ompress ion, the opt imal planning and acqu isi t ion of rpsources, and sythesis of projects under conditions of uncertainty in their structure.The target of this work is concerned with the application of different scientific management tools and techniques for the solution of industrial project scheduling problems of cyclic nature which can generally be viewed as the determination of a feasible project schedule in the form of exact specification for starting and finishing dates for pach ”activity under sets of restrictions arising from precedence, technological and log ical relat ionships: in addition to resource availability and other imposed constraints. Nevertheless, this problem formal izat ion has been categorized according to resouce size availability into -A-, -B-, -C- and -D- modes (In this research work -A-&-B¬modes will be studied).Also,(varying resource)they can be categorized according to esource type or fixed resouce type• and single or multiple to first and second ategory resource type.the subject matter of this thesis is presented in tpe form of seven chapters. Following is the ummary of content for each one.Chapter I introduces the theory of project planning and control• by •network planning techniques • Also, .
