This study proposes a novel option-revenue sharing coordination contract framework. In the proposed model, the retailer determines the number of order sales effort. The manufacturer sets the price of products for the wholesale strategy. The investigated supply chain problem analyzes the results of different strategies. In the proposed coordination contract problem, two types of games including ...
Some products like green vegetables, volatile liquids and others deteriorate continuously due to evaporation, spoilage etc. In this study, an inventory model is developed for deteriorating items with linearly time dependent demand rate under inflation and time discounting over a finite planning horizon. Shortages are allowed and linearly time dependent. Mathematical model is presented for the p...
knowledge of energyconsumption has many uses in industry. factors that are energy dependent have already been studied hence decision making on them are easier. energy demand studies of industry helps us to learn factors that are responsive to this demand. therefore planners can use these collected data in their decision making using the above factors. another use of energy demand can be used as...
The hemipteran (Insecta) diversity in the upper part of the Kerian River Basin was low with only 8 families and 16 genera recorded at 4 study sites from 3 rivers. Water bug composition varied among sampling sites (Kruskal-Wallis χ (2) = 0.00, p<0.05) but was not affected by wet-dry seasons (Z = 0.00, p>0.05). All recorded water parameters were weakly associated with generic abundance but the bi...
In this study, the ecological parameters of the effluent obtained from dyeing of scoured and mercerised organic cotton single jersey fabrics with textile reactive dyes adopting exhaust dyeing method was investigated. The dyes used include regular (Navacron H and FN) reactive dyes and low impact (Remazol and Levafix) reactive dyes along with inorganic salt (sodium sulphate) and biosalt (trisodiu...
Biogas yield of mixtures of cattle slurry and cheese whey, rates of production of methane, removal efficiencies of chemical oxygen demand (COD) and biological oxygen demand (BOD) from the mixtures were investigated at 35°C. Four feed regimens (by volume) were studied. Stable biogas production of 621 l/kg Volatile Solids at an Hydraulic Retention Time of 42 days in a mixture containing 50% slurr...
classical deterministic inventory models consider the demand rate to be either constant or time-dependent but independent from the stock status. however, for a certain type of inventory, the demand rate may be in-fluenced by the stock level. also in many real-life problems, some products such as fruits, vegetables, phar-maceuticals and volatile liquids continuously deteriorate to evaporation, o...
The quest for an effective alternative means for effluent treatment is a major concern of the modern-day scientist. Fungi have been attracting a growing interest for the biological treatment of industrial wastewater. In this study, Saccharomycescerevisiae and Torulasporadelbrueckii were isolated from spoiled watermelon and inoculated into different concentrations of effluent. The inoculants wer...
Four different strategies of pulping and bleaching were carried out to develop alternative mechanistic ecoenvironmental friendly approaches and generated effluent was characterised. Strategy-I included Phanerochaete sp. fungal pretreatment followed by conventional bleaching, whereas in strategy-II, fungal pretreatment was followed by enzyme xylanase aided bleaching. Strategy-III also included x...
OBJECTIVE To determine the most effective and biodegradable dispersant of spilled oil in water surrounding two Persian Gulf provinces. METHODS This study compared the effects of three dispersants, Pars 1, Pars 2, and Gamlen OD4000 on removal of oil in two Persian Gulf provinces' water. Overall, 16 stations were selected. Using the Well method, the growth rate of isolated bacteria and fungi wa...
