An optimal maintenance strategy for cost effective and machine reliability in food manufacturing industries was developed this study. Maintenance parameters were employed to develop cost-reliability based model terms of an using lingo solver. The cost-reliabilitybased considered system’s reliability, equipment failure, preventive maintenance, corrective downtime associated with - maintenance. A...

In this paper, we obtain optimum allocation of replaceable and repairable components in a system design. When repair and replace time are considered as random in the constraints. We convert probabilistic constraint into an equivalent deterministic constraint by using chance constrained programming. We have used the selective maintenance policy to determine how many components to be replaced & r...

In this study, we present the problem of shipping a single-product from a single supply origin, through storage depots, to a single demand destination by trucks, ships, etc. and aim to minimize the sum of ordering, inventory and transportation costs over an infinite time horizon. We formulate the problem consisting of power-of-two (PoT ), stationary and nested replenishment policies for the mul...

Many authors have presented studies of multi-choice stochastic transportation problem (MCSTP) where availability and demand parameters follow a particular probability distribution (such as exponential, weibull, cauchy or extreme value). In this paper an MCSTP is considered where availability and demand parameters follow general form of distribution and a generalized equivalent deterministic mod...

Railway capacity has been a significant issue in the railway industry. Over the last few years, numerous approaches and tools have been developed to compute railway capacity. In this paper, we compute railway capacity to design a topological model for solving periodic train scheduling, developed in collaboration with the National Network of Spanish Railways (RENFE). This topological technique t...

Whilst few studies have explored royalty negotiations for build, operate and transfer (BOT) projects, some works have proposed numerous royalty formulas to evaluate royalty amounts or franchise fees for a BOT project. Despite this, the royalty negotiation process is one of the many critical negotiation items of a concession contract. This study not only developed a royalty negotiation model for...

In this study, a computerized nurse-scheduling model is developed. The model is approached through a 0-1 linear goal program. It is adapted to Riyadh Al-Kharj hospital Program (in Saudi Arabia) to improve the current manual-made schedules. The developed model accounts both for hospital objectives and nurses’ preferences, in addition to considering some recommended policies that are displayed in...

Facility location allocation problem is a very important issue in today's global logistic management. Various facility location problems have been considered in operations research under somehow stringent conditions to reduce the search space. In this paper, we consider a class of single source capacitated facility location allocation problems that can assume more realistic conditions in real l...

Intermodal goods transport is characterized by a main transport by rail, barge or seaborne vessel, preceded and followed by short in time but expensive road transport. Many times trucks pick-up or deliver a single container which leads to a full truckload vehicle routing problem in terms of economically efficient transport services. Time windows induced by the customer or due to external situat...
