摘要:

Highly automated manufacturing systems operate economically only if a high rate of availability of the system is reached. Therefore it is very important to integrate the analysis of system's reliability and availability into the process of planning and designing the structure of the manufacturing system. In this paper planning methods for all kinds of automated manufacturing systems are explained and an example for the availability analysis of a multi-spot welding line is given

摘要:

In examining the basic requirements of warehouse layouts, Berry (1968) called for the use of a simulation model for evaluation purposes. Marsh (1979) provided such a model.

摘要:

This paper gives an approach to the description and modelling of the most widely spread trajectories in modern technology by means of minimum number of stored base positions and orientations. The teaching process of robots under Cartesian path control is discussed and input data for the succession of action, for position, orientation and velocity of the end link (tool or gripper) is specified. An attempt to construct a classification of the different kinds of base points has been made. A real-time control method of tool motion in various coordinate systems in teaching mode is described

摘要:

The paper deals with the role of buffer stock in multi-stage transfer lines by presenting computer simulation results. It is shown that an n-stage line should be designed such that the lowest stage production rate occurs in the nth stage, the second lowest in the first stage, the third lowest in the (n - 1 )st stage, the fourth lowest in the second stage and so on, to maximize line production rate. The paper also demonstrates that the total buffer capacity should be allocated such that (a) the difference between the production rates of the stages on either side of a storage point is minimized, and (b) the production rate of the stages before the storage point is slightly greater than that of the stages following the storage point

摘要:

In the paper is given the original information about the SAPORS system for the automatic design of technological process for NC lathes. The SAPOR-S system is developed at the Laboratory of Machine Tools of the Institute of Production Engineering, Faculty of Technical Sciences, Novi Sad. The model of the system is briefly stated as well as principle of formalizing the input information about the part and some examples of intermediate and final results. Some particularities are emphasized and advantages of the SAPOR-S system over the similar ones. Finally, the directions of further development of the SAPOR system are established

摘要:

Ways of reducing the run-in period and the oil consumption of engines are being investigated intensively. One possible solution is that of making the cylinder liners in such a way that the modification of local geometry during running-in is kept to a minimum. Current technology has developed a modified honing process which attempts to reproduce the run-in texture. However, there are serious problems in measuring these surfaces which is resulting in disputes between machine tool and car manufacturers. This paper analyses the nature and ex tent of a major problem and quantifies it, thereby enabling more rational assessments to be made. Recommendations are put forward for the future

摘要:

In this paper a problem of multi-item production on a single facility is being dealt with. The facility is an electrochemical machining (ECM) system and the products are impact sockets of various sizes for power wrenches. Sequencing production lots in a certain order minimizes set-up time for each new production lot. However, as demand differs from item to item, it is not essential to produce each item in every production cycle. A grouping procedure of the various items is adopted. A modified version of the Page and Paul algorithm is then applied to insure production cycle times which are multiples of the shortest production cycle time. Application of a sequencing policy based on this modified algorithm led to considerable savings

摘要:

This paper suggests a new multidimensional classification method for finding design rules for work groups from the viewpoint of optimizing the interaction of technical, social and organizational factors in work groups. It is called the contingent multidimensional classification method (CMDC)

摘要:

Traditional inventory analysis is based on undiscounted constant cycle costs. Often it has been argued that incorporating the time value of money will not have a significant effect on the lot size. This paper presents discounted cost analysis of a few inventory models. Effect of discounting rate on the economic order quantity is studied. Alternative discounted profit functions are also given
