The flexibility present in a job shop is an important determinant of the future success of the shop, since it increases the ability to deal with the changes a job shop is faced with in a dynamic environment. The presence of idle-time in a job shop schedule contributes considerably to this flexibility. By introducing an anticipation factor that preserves idletime in the scheduling process more f...

TO THE EDITOR—The recent article by Leis et al, “Reducing antimicrobial therapy for asymptomatic bacteriuria among noncatheterized inpatients: a proof-of-concept study” [1], reveals a novel way to manage the problem of unnecessary urine collection. However, this laboratory-based solution proposed by Leis et al does not address the complex behaviors leading to the unnecessary urine collection. I...

UNLABELLED We studied the flocculation mechanism at the molecular level by determining the atomic structures of N-Flo1p and N-Lg-Flo1p in complex with their ligands. We show that they have similar ligand binding mechanisms but distinct carbohydrate specificities and affinities, which are determined by the compactness of the binding site. We characterized the glycans of Flo1p and their role in t...

Image-to-image translation models have shown remarkable ability on transferring images among different domains. Most of existing work follows the setting that source domain and target keep same at training inference phases, which cannot be generalized to scenarios for translating an image from unseen another domain. In this work, we propose Unsupervised Zero-Shot Translation (UZSIT) problem, ai...

We develop a search-theoretic model of the product market that generates price dispersion across and within stores. Buyers differ with respect to their ability to shop around, both at different stores and at different times. The fact that some buyers can shop from only one seller while others can shop from multiple sellers causes price dispersion across stores. The fact that the buyers who can ...

摘要 現場管制系統是ERP的主要子系統之一, 其主要功能是安排現場訂單的排程. 根據研 究,大部分現場的排程問題是屬於 Job Shop問 題. 所以過去幾十年來 Job Shop問題一直是 產業界與學術界重要的研究課題之一. 其間 雖有無數的論文發表, 但因缺少考慮現場實際 的狀況, 很少研究的成果可以用來解決現場的 排程問題. 本研究開發以 Tabu Search為主的 排程方法. 經以個人在美國工作現場所使用之 MRP II 系統所產生的資料驗證, 本方法確能 有效求解現場的排程問題. 關鍵字: Job Shop, Tabu Search Abstract Shop floor control system is a sub-system of the ERP system. Its major function is to generate daily schedules f...

professor of the Owen Graduate School of Management, for his invaluable advice while writing my thesis and my parents whose support has been invaluable. In addition, I am indebted to all the people in the Management of Technology program in particular to Mary Jane Buchanan and Flo Fottrell, thank you for all your help.

In the title compound, C(16)H(12)FlO(2)S, the 4-fluoro-phenyl ring makes a dihedral angle of 80.21 (6)° with the mean plane of the benzofuran fragment. In the crystal, mol-ecules are linked through weak inter-molecular C-H⋯O hydrogen bonds. The crystal structure also exhibits an inter-molecular I⋯F contact [3.423 (2) Å].

We develop a search-theoretic model of the product market that generates price dispersion across and within stores. Buyers differ with respect to their ability to shop around, both at different stores and at different times. The fact that some buyers can shop from only one seller while others can shop from multiple sellers causes price dispersion across stores. The fact that the buyers who can ...

This paper provides a simulation model to study the effect of the work-in-process control on due date performance in job shop environment. The due date performance is measured by both the number of tardy jobs and the total tardiness. The simulation runs include different shop configurations (flow shop and general job shop), workloads and sequencing rules. As expected, the results reveal that du...
