We study a supply chain with one supplier and many retailers that face exogenous endcustomer demands. The supplier and the retailers all try to minimize their own inventory-related costs. In contrast to the retailers’ newsvendor type ordering behavior (under which retailers may place orders freely in every period), we propose two scheduled ordering policies: Scheduled Balanced Ordering Policy (...

The sequential ordering problem (SOP) is the generalisation of the asymmetric TSP in which the tour must obey given precedence relations between pairs of nodes. Many solution approaches have been devised for the SOP, but the version with symmetric costs, which we call the SSOP, has received very little attention. To fill this gap, we present a new 0-1 linear programming formulation for the SSOP...

BACKGROUND Drug resistance (DR) of HIV-1 can be examined genotypically or phenotypically. Although sequencing is the gold standard of the genotypic resistance testing (GRT), high-throughput GRT targeted to the codons responsible for DR may be more appropriate for epidemiological studies and public health research. METHODS We used a Japanese database to design and synthesize sequence-specific ...

Background: HLA compatibility between transplant donor and recipient is one of the major determinants of transplant outcome. Objective: To determine HLA class I by PCR- Sequence-Specific Oligonucleotide Probe (PCR-SSOP) in cord blood donors. Methods: Genomic DNA of 142 cord blood samples registered at the Cord Blood Bank of Iran at Hematology, Oncology, and Bone Marrow Transplantation Researc...

Abstrak : Keamanan pangan (food safety) merupakan salah satu ilmu yang membahas aktifitas pencegahan resiko bahaya fisik, kimia dan biologis selama proses pengolahan pangan. Penerapan keamanan ini sangat krusial mengingat meningkatnya kasus keracunan makanan khususnya pada cepat saji seperti catering, restoran atau rumah makan. Kasus umumnya disebabkan kurangnya penerapan sanitasi higiene. Oleh...

PCR-SSOP identification procedures for IL-2, IL-6, IL-10, TNF-alpha and TNF-beta cytokine polymorphisms have been developed. Application of the procedures to a range of diverse geographically distributed populations has identified ethnic differences within the groups studied. Five populations were investigated, Northern Ireland, South African Zulu, Omani, Singapore Chinese and Mexican Mestizos.

Sanitation practices in the process of slaughtering chickens are very influential on occurrence contamination microorganisms so traditional chicken slaughterhouses (RPA) must apply good production practice procedures or Good Manufacturing Practices (GMP) and sanitation Standard Operating Procedures (SSOP) to produce meat that meets microbiological requirements. This study aims evaluate implemen...

The COVID-19 pandemic has caused people to immobilize eat out, many industries are closed, the community’s economy is down, and online food small medium enterprises (SMEs) have sprung up. One of areas affected by East Jakarta. implementation Sanitation Standard Operational Procedure (SSOP) in SMEs requires special attention during pandemic. This study aims evaluate production facilities SMEs. D...
