In predicting the processing time, the down-time caused by either the failure or the disorder of the equipment must be considered. In this paper, the theory for predicting the processing time including the equipment down-time is presented. Furthermore, an approximate and useful prediction for a shorter processing time is also presented.

This paper presents the scheduling model for a Multi-Stage Process which consists of the pre-process and the post-process. The pre-process is the multi-production plants, and the post-process is the buffers for combined use, This model is reduced to a One-Machine problem under the constraints of the processing time and capacity at the succeeding stations, and is formulated into an Integer-Programming problem by using the 0-1 variables which mean job sequence. In this scheduling model, the Multi-Stage Process problem is eventually formulated into the One-Machine problem to minimize the total flow time under the different due times, job sequence dependent setup times, the earliest and latest end time and restricted working times.

If the shop capacity is limited it may not be possible to make a schedule that leads the completion times of all the parts processed in the shop to be exactly (just-in-time) at their due dates. As a result, the shop may have to incur holding cost for the parts finished earlier. This paper addresses a multi-due-date heterogeneous machines batch-scheduling problem, considering the just-in-time delivery, and the holding cost and the requirement that material to be processed should arrive at the production line just-in-time. We propose a solution procedure that divides the whole planning horizon into a number of periods, allots the parts to be processed in the shop to the divided periods, distributes the parts to be processed in each period to the available machines, and solves the problem of batch-scheduling on each machine. Numerical experience that shows the characteristics of the problem and the computational time required by the proposed procedure is also presented.

We have attempted a new classification scheme of consumer goods by applying the factor and cluster analytical techniques to the data of housewives' purchase behaviors in Osaka area. Results : (1) as for the classification criteria, such factors as purchase frequency, purchase convenience, etc. are effective, especially the purchase frequency, (2) the merchandises in retail stores are clearly divided into frequent and non-frequent purchase goods ; the former is further subdivided into foods and general goods, and the latter into fashionable and durable goods. Consequently, this scheme is almost identical with that of M.T. Copeland on convenience and shopping goods, but does not necessarily deny that of foods and non-foods. Also we found that there was some difference between foods and general goods. although they come under the same category.

In Japanese Industrial Standards (JIS) is provided the single sampling inspection plans having desired operating characteristics by variables in both cases that the standard deviation is known and unknown. JIS Z 9003 (standard deviation known) provides two kinds of assurance criteria for lot quality ; the one is for the mean in lot quality, the other is for the fraction defective of the lot. On the contrary, JIS Z 9004 (standard deviation unknown) is only specified in the case of assuring the fraction defective. In this paper, we study to assure the mean in lot quality when the standard deviation is unknown. In this case it is necessary to assure both the mean and the standard deviation in lot quality, simultaneously. This paper deals with a design problem of single sampling plans by variables for the purpose of assuring both the mean and the standard deviation in lot quality.

This paper deals with the problem for designing a flexible production system by simultaneous introduction of both component part commonality and process flexibility. This paper presents a basis of setting a goal for standardizatiom of component part and for designing flexible manufacturing system for a two-stage fabrication/assembly process, analyzing the relationship between the component part commonality and process flexibility in terms of manufacturing performance.

In the part I, we proposed a model formulation to decide the number of Kanbans by the goal programming and then considered the following JIT factors : demand, in process inventory, inventory and labor costs, subcontractor's supply capacity, and work load. In this paper, we propose a mixed integer goal programming model taking into account the factors stated above. This model decides the number of kanbans while considering both the container size in each process and also the flow of different types of processes (corresponding to different items) in a multi-stage manufacturing system. Finally, we present a numerical example in order to verify our model.

A full functional FMS (FF-FMS), in which each machining center has all of the tools required for processing various kinds of jobs, is superfluous and wasteful in meeting changeable demands in a flexible manner. To reduce the redundancy and to obtain the utilization as high as that of the FF-FMS, we proposed methods for distributing tools to each machining center in a two-machine, jobshop-type, partly separated functional FMS (PSF-FMS) having some duplicated tools. In this paper, we propose a method for distributing tools in a jobshop-type PSF-FMS having more than three machines. Some simulation results demonstrate the effectiveness of the proposed method for achieving the high utilization of the PSF-FMS with less amount of duplicated tools.

In a cellular manufacturing system, it is desirable that production processes of the parts in a part family can be completed in only one manufacturing cell. But, some parts may move to another machine belonging to different cells. These intercell moves are called "Exceptional Elements (EE)" in 0-1 machine-part matrix. Three operations (machine duplication, part elimination, and rearrangement of part families) are necessary to make an independent cell without EE. In this paper, we propose a method to form the independent cells with maximum grouping efficacy by taking the appropriate operations to eliminate EE.

The paper presents an economic production quantity model in which a fraction β(t) (backorder ratio) of the demand is backordered and the remaining fraction 1-β(t) is lost during the stockout period. Under the assumptions of deterministic demand rate and deterministic production rate, an objective function representing the annual cost of a production system by defining a time-weighted backorder cost and a lost sales penalty cost per unit lost is developed. This paper suggests a numerical iteration method for the solution of economic production quantity and stockout quantity per period by definingβ(t) function representing the backorder ratio when backorder time is t. In case β(t)=1,the presented model reduces to the Fabrycky's model with complete backorders.
