Proposition 1. Consider two stocking policies s1 and s2 where for some j , s2 j = s1 j − 1, s2 j−1 = s1 j−1 + 1, and s2 i = s1 i , ∀ i = j j − 1. We have that: (i) ILi s2 i s 2 N ≥ ILi s1 i s1 N for i ∈ 1 j − 1 , and (ii) ∑j i=1 Bi i s 2 i s 2 N ≥ ∑j i=1 Bi i s 1 i s 1 N . Proof. From (6) and (7) we find that ILj s2 j s 2 N = ILj s1 j − 1 s1 j+1 s1 N = ILj s1 j s1 N − 1. Thus from (8) and (9), ...

Let’s consider m providers (distributors, manufacturers, etc.) F1 − Fm of an identical product that they possess in quantities a1 − am as well as n consummers or beneficiaries (users) B1 − Bn whose needs are b1 − bn . Let us denote by xij the quantity that is transported (transferred, allocated) from Fi to Bj and with cij as unit transportation costs from Fi to Bj. The cost of transportation fo...

Glutamate is the major excitatory neurotransmitter in the brain. It can cause neuronal cell damage in the context of oxidative stress. BJ-1201 is a derivative of the compound aminopyridinol, which is known for its antioxidant activity. In this study, we examined the effect of BJ-1201, a 6-(diphenylamino)-2,4,5-trimethylpyridin-3-ol compound, on neuroprotection in HT22 cells. Our data showed tha...

در این مقاله یک مدل ریاضی برای مسئله سیستم تولیدی همکارانه ساخت بر اساس سفارش با رعایت انصاف تخصیص بار‌های تولید طراحی شده است. اهداف اصلی مدل، کمینه‌سازی هزینه‌‌های کل و حداکثر استفاده از منابع به‌منظور عادلانه شرایط عدم­قطعیت کنترل پارامتر‌های غیرقطعی روش برنامه‌ریزی فازی ‌شده نتایج نشان می‌دهد افزایش نرخ عدم‌قطعیت، می­یابد. ازآنجاکه ظرفیت کارخانه‌ها ثابت است، مقدار تقاضا، هر کارخانه نیز می­ی...

Definition 1. Given a vector |v〉 ∈ H, by a Schmidt decomposition across the (i, i + 1) cut we shall mean a decomposition |v〉 = ∑j=1 λj|aj〉|bj〉 with {|aj〉} (respectively {|bj〉} ) a family of orthonormal vectors of H[1,i] (respectively H[i+1,n]) and with λj ≥ λj+1 > 0 for all 1 ≤ j ≤ D. The vectors |aj〉 will be called the left Schmidt vectors across that cut, and the vectors |bj〉 the right Schmid...

Jump height is a critical aspect of volleyball players' blocking and attacking performance. Although previous studies demonstrated that creatine monohydrate supplementation (CrMS) improves jumping performance, none have yet evaluated its effect among volleyball players with proficient jumping skills. We examined the effect of 4 wk of CrMS on 1 RM spike jump (SJ) and repeated block jump (BJ) per...

AKL(FD) is an integration of (an extension of) the nite domain constraint system FD in AKL, a deep concurrent constraint programming language CJH94]. In this paper we describe the implementation of the FD solver and its adaptation to the generic constraint interface of the AGENTS implementation of AKL. We also describe compilation techniques used by the AKL(FD) compiler. 1 Introduction Conceptu...
