Rework remains an ever-present reality in construction projects. How rework data is defined, its format, location, and quantification contribute to the difficulty managing risks. This paper examines challenges acquired learnings encountered while attempting create curate a domain ontology construction. An explanatory case study approach utilizing lens of pragmatism used develop real-life transp...

Fast-track construction projects have become more popular in recent years in response to growing industry demand. By allowing a downstream activity to start with incomplete information from upstream activities, fast-tracking allows for shortening the project duration at the expense of an increased likelihood of rework. This leaves practitioners with the challenge of determining the optimal fast...

Pekerjaan kontruksi yang terjadi di lapangan tidak selalu sesuai dengan rencananya. Penyimpangan sering ditemukan pada pekerjaan finishing, karena dalam pengerjaannya membutuhkan ketelitian dan kerapian. Akibat penyimpangan ini maka harus dilakukan ulang atau rework rencana kualitas mutu perusahaan diterima oleh konsumen. Faktor dapat menyebabkan antara lain faktor desain, manajerial sumber day...

Determining the risk and uncertainty of rework in construction has received limited attention due to a paucity information about its frequency causes. Errors made during construction, which may require rework, can go undetected, manifesting as an engineering failure asset’s operation thus jeopardise system safety. Therefore, this paper addresses following research question: How practitioners ma...

Generally speaking, wafer fabrication factories define the photolithography area as the dispatching center of the entire factory. To establish a set of operative dispatching rules in the photolithography area while taking into consideration the rework of defective products would assist in coordinating and balancing the workload of the entire production line. Furthermore, it would help to enhanc...

Long run average costs for finite production rate model with backlogging is less than or equal to that of the same model without backlogging. An equation for calculating intangible backorder cost is proposed for situation when required service level is not attainable. By incorporating this intangible backorder cost in mathematical analysis, one can derive a new optimal lot-size policy that mini...

Avoidable rework consumes a large part of development projects, i.e. 20-80 percent depending on the maturity of the organization and the complexity of the products. High amounts of avoidable rework commonly occur when having many faults left to correct in late stages of a project. In fact, research studies indicate that the cost of rework could be decreased by up to 50 percent by finding more f...

Globalization has created tremendous opportunities, but also made business environment highly competitive and turbulent. To gain competitive advantage, management of present-day transnational firms always seeks options to trim down various transaction and coordination costs, especially in the area of controllable intra-supply chain system. This study investigates a multi-product intra-supply ch...

This study attempts to determine the optimal production run time for an economic production quantity (EPQ) model with a Poisson breakdown rate, the rework of nonconforming items, and multi-delivery of finished products. It is assumed that nonconforming items can be randomly produced and repaired through a rework process added at the end of the production process. Production equipment is subject...

Fast-track construction projects have become more popular in recent years in response to growing industry demand. By allowing downstream construction activities to start with incomplete information from upstream design activities, fast-tracking (through overlapping) allows for shorter project duration at the expense of potential rework. This leaves practitioners with the challenge of determinin...
