In this paper, we will address the cyclic scheduling problem with limited WIP (Work-in-process). In these systems, we have to minimize the cycle time of the production while working with a limited level of WIP. We consider here production systems with linear jobs (every operation was followed and preceded by only one operation). Many methods have been proposed to solve the cyclic scheduling pro...

LINC (linker of nucleoskeleton and cytoskeleton) complexes play an essential role in nuclear migration by connecting the nucleus to the cytoskeleton and/or motor proteins. Plant LINC complexes have recently been identified in Arabidopsis thaliana, with the inner nuclear membrane SUN and outer nuclear membrane WIP proteins comprising the first identified complex. A recent study identified a nucl...

Forecasting the work-in-process (WIP) level is very important for the control of factory. However, the uncertainty in the WIP level is not easy to deal with. To solve this problem, a fuzzy collaborative forecasting approach is proposed. And also we show the effectiveness of the proposed methodology with a case study.

Understanding the toxicity of oil sands process-affected water (OSPW) is a significant issue associated with the production of oil from the Alberta oil sands. OSPW is acutely and chronically toxic to organisms, including larvae of Chironomus dilutus. In this study, fresh OSPW ('WIP-OSPW') was collected from the West In-Pit settling pond and aged OSPW ('FE5-OSPW') was collected from the FE5 expe...

Purpose – Since lean manufacturing considers that “Inventory is evil”, the purpose of this paper is to find and quantify the relations between work-in-process inventory (WIP), manufacturing lead time (LT) and the operational variables they depend upon. Such relations provide guidelines and performance indicators in process management. Design/methodology/approach – The authors develop equations ...

The accurate cycle time (CT) prediction of the wafer fabrication remains a tough task, as system level work in process (WIP) is fluctuant. Aiming to construct one unified CT forecasting model under dynamic WIP levels, this paper proposes transfer learning method for finetuning predicted neural network hierarchically. First, two-dimensional (2D) convolutional was constructed predict primary with...

Serial flow or production lines are modeled as tandem queueing networks and formulated as continuous-time Markov chains to investigate how to maximize throughput or minimize the average work-in-process (WIP) when the total service time among the stations are fixed (this is the workload allocation problem). This paper examines the effect of the unreliability of the machines on the optimal worklo...

The current trend among manufacturers is to reduce WIP by decreasing the lot size. Reducing the lot size in some cases may have an adverse effect on system performance because more setup time is incurred. In this paper, we propose the use of queueing network models to determine the best lot-sizing policy that minimizes the WIP. The queueing network model is validated by comparing its results to...
