Multiple-Floor Facility Layout Design with Aisle Construction

Industrial Engineering and Management Systems, volume 5, issue 1, 2006, Pages 1~10
This proposed research focus on an aisle construction system for automated multiple-floor facility layout problem with indoor and outdoor consideration. First, clustering technology is applied to classify departments, based on relationship of flow among departments, free spaces in plane, and dimensions of departments. These departments, which belong to the same group, allocate into the same floor. Then the system generates initial layout with considerations of feasible solution and shortest path among sub-facility. Finally, hybrid genetic algorithm is used to improve initial layout. To enhance the practicality of the proposed research, a computer program is developed to suggest location and indoor of each department with distribution of aisle. Simulation results, which were compared with the results of exhaustive search and previous work, show very highly performance on the total material handling cost and computational time.

Kanban has been known as a superior tool to control a complex production and inventory system. Even if this tool operates well using a local rule without any detailed ordering schedule, a production planning is still neces-sary to determine production capacity and the number of kanbans. The production planning is made in consideration of a monthly forecasted demand while the kanban orders production and procurement several times a day. For an effective use of the kanban system, an integration of the monthly production planning to the kanban system will become important. In this study, we propose an integrated production planning problem in which the number of kanbans for each of multiple items as well as production quantity and production capacity during several months is determined. The problem formulated in this paper will be hard to solve exactly since the problem contains many integer decision variables and nonlinear constraints. In order to solve the problem efficiently, a decomposed problem is solved after making linear relaxation of integer variables. A numerical example is solved to show effectiveness of the proposed model.

Project management (PM) deals normally with different information variables that form a dynamic and high dimensional information space. Although better understanding from this space leads to more intelligent PM process, traditional PM methods cannot capture the complexity and dynamic nature of project information space. One way to overcome this problem is integrating system dynamics (SD) concept and traditional PM tools for providing better vision of dynamic behavior of project but some problems remain unsolved. For example, hidden information, the information lie among the relationships of accessible project information and SD's level variables, are not recognized. Solving this problem is the main motivation of this research. The main idea is integrating Self-Organizing Maps (SOM) and SD to map project's high dimensional information space into a two- or three-dimensional one. This decreases the complexity and leads to reveal more information about project condition and trend. In this way, many potential risks and disturbing events may be identified and managed easily. The proposed method is not only a PM analysis tool but also a unique reporting system that makes it possible to visualize the project condition.
Decomposition-based Makespan Minimization in Job Shops

This paper proposes a decomposition-based heuristic approach to minimizing the makespan of job shops. In general, decomposition methods first divide the whole problem into several sub-problems, solve them and then combine sub-schedules to obtain a good feasible schedule. Although it may be reasonable to minimize the makespan of each sub-problem, its optimality will be lost when combining sub-schedules and making the whole schedule be feasible. If each sub-schedule is relatively insensitive to the uncertainty of processing times, this property may weaken the relationship between sub-schedules, and a feasible solution may be obtained without affecting the optimality so much. Based on this idea, a minimum instability schedule is selected from the set of makespan-minimum active schedules as the solution for sub-problems. The minimum instability schedule is the least sensitive schedule against the one time unit of completion delay in an operation. Three benchmark problems were solved to examine the effectiveness of adopting the minimum instability schedules. The results indicated that the minimum instability sub-schedules often produced better whole schedules when compared with the schedules based on the maximum instability sub-schedules.
A Level Crossing Approach to the Finite Dam with D-policy
Chae, Kyung-C. ; Park, Yonil ; Xeung-W., ;
Industrial Engineering and Management Systems, volume 5, issue 1, 2006, Pages 39~42
Using the level crossing technique, we present a transform-free analysis of a finite dam with D - policy. The input process is a compound Poisson process. An accumulation period and a release period constitute a regeneration cycle. A release period begins at the instant the amount of water accumulated during the preceding accumulation period exceeds D. The output rate is one during a release period. The next accumulation period begins at the instant the dam becomes empty.
Dynamic Inventory Model
Kodera, Jan ; Marek, Petr ;
Industrial Engineering and Management Systems, volume 5, issue 1, 2006, Pages 43~47
Contemporary theoretical inventory models do not usually comply with practical requirements because of their linearity and stationarity. A model called "Economic Order Quantity" focuses only on two main factors: order costs and carrying costs. At the same time it is based on very strict assumptions. Our aim is to establish a dynamic inventory model and to introduce a new factor into this model i.e. interest rate. The objective functional of the model is the present value of cash flows. The model is drawn as an optimal control problem and is solved with the help of the Pontryagin principle.
Fundamental Principles and Viewpoints of Manufacturing Revolution Activities
Kono, Hirokazu ;
Industrial Engineering and Management Systems, volume 5, issue 1, 2006, Pages 48~56
Many Japanese manufacturers are implementing various production revolution programs for their survival in the ever more severe business environment. Among those diverse programs, this paper investigates two that are attracting considerable attention in practice: 'outsourcing' of production function, and 'cell production system' introduced in many assembly lines. Both of these activities are expected to generate sizeable performance improvement results, the former by concentrating management resources on core business areas while cutting off non-core operations of the business, and the latter by making a leap in productivity at assembly lines. This paper first discusses concepts of 'outsourcing' and 'cell production system' in order to clarify often-forgotten key points to be noted in adopting them, while paying attention to the mechanism of how each of these concepts achieves business performance results. The paper presents viewpoints needed in evaluating these concepts from managerial viewpoints and considers each viewpoint citing practical cases. This paper then goes on to present three basic principles to be remembered in implementing truly fruitful productive innovation, giving views on managerial guidelines for implementing them.
