Motives: One of the final indicators service reliability transport system is cargo delivery time, compliance which not yet controlled due to lack appropriate methods and tools operational management. The concept quality assessment delivery, namely with time obligations by transportation participants, associated process modeling accuracy determination estimated completion each stage technologica...

This paper proposes a novel, bi-objective mixed-integer mathematical programming for an open shop scheduling problem (OSSP) that minimizes the mean tardiness and the mean completion time. To obtain the efficient (Pareto-optimal) solutions, a fuzzy multi-objective decision making (fuzzy MODM) approach is applied. By the use of this approach, the related auxiliary single objective formulation can...

In this paper, a new method for developing a lower bound on exact completion time distribution function of stochastic PERT networks is provided that is based on simplifying the structure of this type of network. The designed mechanism simplifies network structure by arc duplication so that network distribution function can be calculated only with convolution and multiplication. The selection of...

Initially designed for independent datas, low-rank matrix completion was successfully applied in many domains to the reconstruction of partially observed high-dimensional time series. However, there is a lack theory support application these methods dependent datas. In this paper, we propose general model multivariate, We show that least-square method with rank penalty leads error same order as...

the issue of successful project management and control is of vital importance in today’s world. although the time and cost of any project is determined in advance, paying less attention to an appropriate control and revision will result in a small chance of reaching those goals. the earned value management method that shows deviation of projects schedules and costs is of the good method for thi...
