Among the multitude of activities of Hajj Organization which require careful planning bus assignment to the Iranian pilgrim caravans d g pilgrimage is the most important one. The objective of this assignment is to have a minimum number o standing passengers/empty seats, while satisfying a large number of operational and religious constrain. This problem was formulated as a large scale zero-one ...

In this thesis we explore how to utilize a loop cache to relieve the unnecessary pressure placed on the trace cache by loops. Due to the high temporal locality of loops, loops should be cached. We have observed that when loops contain control flow instructions in their bodies it is better to collect traces on a dedicated loop cache instead of using trace cache space. The traces of instructions ...

With the advance in remote sensing, various machine learning techniques could be applied to study variable relationships. Although prediction models obtained by using machine learning techniques are suitable for predictions, they do not explicitly provide means for determining input-output variable relevance. The relevance information is often of interest to scientists since relationships among...

We investigate the relationship between the state assignment of the sequential machine and the observability of a faulty internal state on the primary outputs for faults that result in unidirectional errors. We state sufficient conditions for faulty states to propagate to primary outputs in one clock cycle and use them to derive the constraints that must be imposed on the state assignment of th...

This paper addresses the common cycle multi-product lot-scheduling problem in flexible flow lines (FFL) where the product demands are deterministic and constant over a finite planning horizon. Objective is minimizing the sum of setup costs, work-in-process and final products inventory holding costs per time unite while satisfying the demands without backlogging. This problem consists of a combi...

In today’s highly competitive manufacturing environment, process data monitoring continues to be of high priority, but often relies on modern communication interfaces being provided by PLC manufacturers. This paper proposes an alternative approach in which is acquired automatically from various models through available interfaces. Multiple Machine Learning algorithms are incorporated identify m...

The author’s simple universal Turing machine requires the description of a specific Turing machine as data. In this article the coding of a specific Turing machine for unary multiplication is described. The description is a list of transitions with unary coded links between them. The order of the transitions in the list therefore makes a large difference in the size of the resulting code and th...

Assignment model is a powerful operations research techniques that can be used to solve assignment or allocation problem. This study applies the assignment model to the course allocation problem in Nigeria tertiary institution in order to maximize lecturers’ effectiveness. A well-structured questionnaire was used to obtain data from lecturers and solved with Hungarian method. The study revealed...

The problem of task assignment in heterogeneous computing system has been studied for many years with many versions. We consider the problem in which tasks are to be assigned to homogeneous and heterogeneous machines to minimize the sum of the total computation and communication costs. In this paper, we introduce a novel algorithm to solve task assignment problem. It optimizes the assignment of...
