Processing mail objects in a mail processing center involves several steps and operations, in particular dispatching as well as sorting by destination. The purpose of this paper is to present a model for the part-time worker staffing and allocation proble
Wireless LAN systems have been widely implemented for supporting the sireless internet services especially in the hotspot areas such as hospitals, homes, conference rooms, and so on. Compared with wired LAN systems, wireless LAN systems have the advantage
Member's perception toward organizational climate is an abstract concept but generally it has been used in the meaning of Organizational climate by members, in an attempt to give an idea of what kind of meaning an organization can have from a psychologica
In an environment of global competition, the success of a manufacturing corporation is directly related to bow it plans and executes production in particular as well as to the optimization level of its process in general. This paper proposes a production
In this article, scheduling of a casting sequence is studied in casting foundry which must deliver products according to the Just-in-time(JIT) production policy of a customer. When a foundry manufactures a variety of casts with an identical alloy simultan
Healthcare organizations need mutual cooperation among various medical professionals in order to carry out the performance of their duties spite of having a strong job specialization and independence based on license. However, spite of the importance of l
This study is the result of meta evaluation for the self evaluation of defense R&D programs in Korea by using meta evaluating indicators. The overall meta evaluation result of defense R&D programs gained 74.3 points out of 100, so it was ecaluated as 'Goo
Using the results of the expected busy periods for the dyadic Min(N, D) and Max(N, D) operating policies in a controllable M/G/1 queueing model, an important relation between them is derived. The derived relation represents the complementary property betw
The purpose of this study was to compare gait patterns during pregnancy. Because of the changes in hormone levels and anatomical changes such as body mass, body-mass distribution, joint laxity, and musculotendinous strength that result from pregnancy, it
A lot of B2C Internet shopping mall companies are establishing various strategies in order to make a result to be further better than it. But They are experiencing trouble by restriction like manpower or financial issue. Therefore, trying to grasp how an
This paper studies that б values(10, 20, 50)and ρ values (-0.6, -0.3, 0.0, 0.3, 0.6) affect the total inventory cost of a supply chain and order fill rate when the market demand process follows a general auto-correlated AR(1) process without seasonality.
Negative binomial yield model for semiconductor manufacturing consists of two parameters which are the average number of defects per die and the clustering parameter. Estimating the clustering parameter is quite complex because the parameter has not clear
This paper introduces a case study for efficient generation of production schedules in a tube manufacturing system. The considered scheduling problem consists of two sub problems : lot sizing for a job and job sequencing. Since these problems require simu
This research investigates the problem of minimizing setup costs in resequencing jobs having first-in, first-out(FIFO) constraints at conveyorized production or assembly systems. Sequence changing at conveyor junctions in these systems is limited due to F
RAM(Reliability, Availability, Maintainability) is important performance factor to keep combat readiness and optimize operational and maintenance cost of weapon systems. This paper discusses the method to establish RAM for combat readiness by using field
A variety of statistical methods are applied to model and optimize responses, related to product or system's quality, in terms of control and noise factors at design and manufacturing stages. Most of them assume continuous response variables but, assessin
The supplier selection problem is perhaps the most important component of the purchasing function. Some of the common and influential criteria in the selection of a supplier include quality, price, delivery, and service. These evaluation criteria often co
In this paper, we consider a single-vendor single-buyer supply chain problem where a single vendor order raw materials from its supplier, then using its manufacturing processes converts the raw materials to finished goods in order to deliver finished good
The proliferation of the internet and electronic commerce has given the manufacturers the opportunity of direct marketing. This study analyzes the decision of manufacturers regarding whether to sell the products through independent sales company or to sel
