Managing the Company in the Setting of Implementing Large-Scale Development Programs

Abstract

This article examines issues of streamlining project management systems in the setting of implementing large-scale company development programs.The primary aim of this work is to present a methodological approach towards the development of specific functional areas of project management and the formation of a baseline plan for the implementation of the project, which consists of three major documents -a content management plan, a baseline schedule, and a project cost management plan. The work provides methods and algorithms for the formation of baseline plan results and qualitative and quantitative assessment of risks and the project budget.At the same time, the author provides a number of limitations to the use of the proposed methodology, the most crucial of which deal with companies' lack of specialists possessing the necessary level of professional competencies, lack of special programming solutions on the automation of project management systems, and the labor intensity of accurate and full quantitative assessment of possible damage in case of a risk event arising.

Developing a Mathematical Model for Scheduling and Determining Success Probability of Research Projects Considering Complex-Fuzzy Networks

“…First, the lowest classified level in the loop shall be prioritized and based on such priority, the loops of this level shall be solved in the selected complex loop, and their impacts shall be applied based on step (6). Then, process of prioritization shall be executed for the loop at one upper level in this complex loop.…”

“…A major part of projects is conducted in research organizations and institutes especially military ones. These projects have certain features including [1,2] (1) uncertainty in defining the activities, (2) unclear and uncertain results of activities, (3) uncertainty in time and cost of activities, (4) noniterative activities, (5) loops and iterations to previous activities, and (6) parallel paths. Due to such features, a certain technique is needed to deal with such projects under determined time and cost effectively.…”

“…(3) to provide a new mathematical model for removing delay or reversible-to-itself branches in fuzzy networks, (4) to provide a new mathematical model for removing simple and subindependent complex loops in fuzzy networks based on transformation to reversible-toitself branches, (5) to provide an algorithm for estimating of PCT and scheduling of the simplified (no loops) fuzzy networks, based on equivalent making of parallel and series branches, (6) to provide a new mathematical model for estimating of the probability of project success.…”

“…The results showed proper and real performance of models in comparison with existing methods.Journal of Applied Mathematics methods, that is, CPM (Critical Path Method) and PERT (Program Evaluation and Review Technique), were introduced and developed [6].Project management, in particular, project planning, is a critical factor in the success or failure of new product development (NPD) [7] and research and development (R&D) projects [8]. Limited facilities of CPM and PERT methods for modeling of projects having complex and uncertain networks [6] caused the great scientists such as Pritsker and Whitehouse [9] and Pritsker and Happ [10] to introduce the probability GERT (Graphical Evaluation and Review Technique) which is a method consisted of flow graph theory, moment generation functions, and PERT to solve problems with probability activities. Pritsker [11] developed GERT method and used it for different nodes and introduced use of simulation in that method.…”
