Vendor managed inventory (VMI) is a supply chain partnership strategy that allows a supplier to place orders on behalf of its customers. This paper considers a supply chain composed of a single vendor and multiple retailers operating under a VMI contract that specifies limits on retailers' stock levels. We address the problem of synchronizing the vendor's cycle time with the buyers' unequal ordering cycles by developing a mixed integer non-linear program that minimizes the joint relevant inventory costs under storage restrictions. We also propose a cost efficient heuristic to solve the developed optimization problem. We conducted computational experiments to assess the reduction in the total supply chain costs resulting from relaxing the restriction of equal ordering cycles. It is found that the heuristic generates greater cost savings in cases of increased variability in retailers' demand and cost parameters. 相似文献

INTRODUCTION: Disseminated tuberculosis, i.e., tuberculosis involving lung, liver, spleen, bone marrow and lymph nodes is rare (2.8%), particularly when immunocompromised diathesis is lacking. EXEGESIS: We report three cases of disseminated tuberculosis confirmed by bacteriology or histology, which occurred in non-immunocompromised patients. Disease evolution under antituberculous treatment was favorable in two cases and fatal in the third one. CONCLUSION: Disseminated tuberculosis must be suspected when miliary pulmonary lesions are associated with hematologic abnormalities, even in non-immunocompromised host. Early treatment is mandatory to avoid fatal outcome. 相似文献

Neuroendocrine tumors (NET) of the digestive system are rare. They comprise only 1% of all the tumors of the gastrointestinal tract. The aim of this study is to report two cases of exceptional localization of non secretary neuroendocrine tumors. Their difficulty in diagnosis, treatment and controversy in chemotherapy merit their study in depth. These are two patients that were treated in the department of general surgery (Beau Séjour) in Charles Nicolle Hospital for non secretary (NET) of the pancreas and stomach. The first was presented as a painless epigastria mass with frequent diarrhea. The second was presented as a painful mass in the left hypochondriac area without any other symptoms. Biochemical evaluation confirmed their non secretary properties. Surgery remains the first line of treatment. It was possible for the gastric, but not for the pancreatic tumor. Both were very advanced and had metastasis. Histopathological evaluation and immunohistochemical study using the method of peroxydase antiperoxydase (PAP) complexes for some special monoclonal antibodies confirmed the diagnosis. Chemotherapy of both cases was mal tolerated and was discussed in details. 相似文献
