Drum–Buffer–Rope is a theory of constraints production planning methodology that operates by developing a schedule for the system’s first bottleneck. The first bottleneck is the bottleneck with the highest utilization. In the theory of constraints, any job that is not processed at the first bottleneck is referred to as a free good. Free goods do not use capacity at the first bottleneck, so very...

The cyclic permutation flow shop is one flow shop that repetitively produces product mix under permutation schedules. We propose that the cyclic permutation flow shop given the general job sequence can be modeled as a time event graph, based on which the mixed-integer programming method is applied to find the optimal schedule with maximum throughput. Two cases of cyclic permutation flow shops w...

In this paper we consider an infinite buffer fluid model whose input is driven by independent semi-Markov processes+ The output capacity of the buffer is a constant+We derive upper and lower bounds for the limiting distribution of the stationary buffer content process+We discuss examples and applications where the results can be used to determine bounds on the loss probability in telecommunicat...

We consider scheduling packets with values in a capacity-bounded buffer in an online setting. In this model, there is a buffer with limited capacity B. At any time, the buffer cannot accommodate more than B packets. Packets arrive over time. Each packet is associated with a non-negative value. Packets leave the buffer only because they are either sent or dropped. Those packets that have left th...

Four presumptive blood tests, Hexagon OBTI, Hemastix(R), Leucomalachite green (LMG), and Kastle-Meyer (KM) were compared for their sensitivity in the identification of dried bloodstains. Stains of varying blood dilutions were subjected to each presumptive test and the results compared. The Hexagon OBTI buffer volume was also reduced to ascertain whether this increased the sensitivity of the kit...

Under the influence of pathological factor, there is a change in intensity lipid peroxidation, accumulation blood concentration products free radical oxidation and reactive oxygen species, decrease buffer capacity relative to maintenance optimal parameters extreme reactions. The work aimed investigate effect feed additive “Sylimevit” on antioxidant protection body dogs after preventive dewormin...

abstract: this research was done to determine the effect of using l-carnitine and selected exercises on aerobic capacity and blood lactate. in this study 30 unathletes students of shahid rajaee university took part with the age of 22/63±1/75, height: 176 cm, weight 71/33±1 and bmi: 23/17±2/6. subjects randomly divided into 3 groups, control group who were doing the selected exercises, experimen...

Harbor porpoises are active divers that exchange O(2) and CO(2) with the environment during a fast single breath upon surfacing. We investigated blood O(2)-transporting properties, buffer characteristics, Cl(-) transport via the erythrocyte anion exchanger (AE1), circulating nitric oxide metabolites and hemoglobin nitrite reduction in harbor porpoises with the aim to evaluate traits that are ad...
