On-line Control Model for Cost-simulation Network Projects

Task assignment with multiskilled employees and multiple modes for product development projects

“…One of the major problems of a product development project management is that the duration of a task involved in the project may be difficult to predict accurately [4] due to task iterations. The well-known program evaluation and review technique and critical path method techniques [5,6] describe development processes with task duration estimates and precedence relationships representing the network of development activities only if activities are sequential and/or parallel. These models ignore iterations or implicitly incorporate iterations into duration estimates.…”

Multi-objective time–cost trade-off in dynamic PERT networks using an interactive approach

“…Golenko-Ginzburg and Gonik [18] developed a hierarchical on-line control model for several PERT type projects being realized simultaneously. This model has two objectives: to minimize the number of control points and to maximize the probability that the slowest project can meet its due date on time.…”

“…This model has two objectives: to minimize the number of control points and to maximize the probability that the slowest project can meet its due date on time. The paper by GolenkoGinzburg and Gonik [19] is a further development of [18], which is applied to projects with variable speeds like building projects. To speed up the model's performance, Golenko-Ginzburg and Gonik [20] presented an online heuristic control algorithm, in which the timing of inspection points does not comprise intermediate check-points and is based on the behavior of a risk averse decision-maker (DM).…”

This paper is a further development of [18,19]. Golenko-Ginzburg et al [21] developed a heuristic approach to determine both control points and speeds to be introduced at those points, in order to minimize the production system's expenses within the planning horizon.…”

“…The above stochastic models are all static in sense that the number of projects, which is considered in the model, is either one like Arisawa and Elmaghraby [1], Azaron et al [3,4], Laslo [28] and Golenko-Ginzburg et al [14,[19][20][21][22] or a fixed number of PERT type projects being realized simultaneously at the beginning of each algorithm like Golenko-Ginzburg et al [15][16][17][18], but in our proposed model projects are generated consecutively according to a renewal process, which is the main contribution of our paper. The existing models are mainly appropriate to plan and control R&D projects and long-term projects when designing or developing new industrial or populated areas, but our proposed model is appropriate in the building construction, when creating and building similar successive installations along the time horizon.…”
