Rework that is often experienced in construction projects is primarily caused by errors made during the design process. Factors that contribute to design errors are identified and used to design and develop a systems dynamics model, which is used to simulate a number of practical scenarios that can be used to reduce design errors and rework. The DEsign and COnstruction REwork Minimisation (DECO...

One of the important problems in the field of Construction Industry is ‘rework’. It affects time, costs, quality, and almost every criteria of project success. As a result of rework and ineffective use of resources and materials in the workshops, there is always a considerable loss of resources, materials, investments, and workforce-time. Designing and planning through full awareness of clients...

This paper presents a framework for optimizing the location(s) and characteristics (fault coverage/test cost, rework success rate/rework cost) of Test/Diagnosis/Rework (TDR) operations in the assembly process for electronic systems. A new search algorithm called Waiting Sequence Search (WSS) is applied to traverse a general process flow in order to perform the cumulative calculation of a yielde...

this paper deals with the single machine multi-product lot scheduling problem in which defective items are produced in any production run of each product. we have adopted the common cycle scheduling policy and assumed that the setup times for production of each product can be non-zero. further, we have assumed that defective items will be reworked and the inspection costs during the normal prod...

We study the problem of planning the production of new and recovering defective items of the same product manufactured on the same facility. Items of the product are produced in batches. The processing of a batch includes two stages. In the first work stage, all items of a batch are manufactured and good quality items go to the inventory to satisfy given demands. In the second rework stage, som...

It is known that Moufang loops are closely related to groups as they have many properties in common. For instance, they both have an inverse for each element and satisfy Lagrange’s theorem. In this paper, we study the properties of a class of Moufang loops which are not groups, but all their proper subloops and proper quotient loops are groups.

one hundred and eight male (108) cases, which have been using lippes loops (i.u.d.) for contraception, were followed for five (+5) years, and unwanted pregnancies and side effects were analyzed. our over all impression is that because of the frequency of uterine bleeding which they cause, lippes loops are not an ideal contraceptive method for iranian women.

Rework is an interesting topic in the contract management of construction projects. An effective way improving performance on projects to manage rework. However, managing rework challenging because dynamic nature activities. A rational starting point identification root causes then a framework for its can be developed performance. This paper reviews rework-related studies industry through criti...
