An integrated reliable five-level closed-loop supply chain with multi-stage products under quality control and green policies: generalised outer approximation with exact penalty

Abstract: In this paper, we design and optimise an integrated five-level Supply Chain (SC), which contains a supplier, a producer, a wholesaler, multiple retailers, and a collector. Accordingly, a Closed-loo...

Provide a practical approach for measuring the performance rate of organizational strategies

Abstract: Strategic management focuses on integrating management, marketing, production/operations, finance/accounting, research and development, and information systems to achieve organizational success. Strategic management allows Organization to make effective long-term decisions, to execute those decisions efficiently, and to take corrective actions as needed to ensure success. Evaluating strategies on a continuous rather than on a periodic basis allows benchmarks of progress to be established and more effectively monitored. Strategy evaluation is the primary means for obtaining this information. Effective strategy evaluation allows an organization to capitalize on internal strengths as they develop, to exploit external opportunities as they emerge, to recognize and defend against threats, and to mitigate internal weaknesses before they become detrimental. A key to effective strategy evaluation and to successful strategic management is an integration of intuition and analysis. In this study, dimensional analysis method has improved and base on Freeman model, has been presented new method that determine performance rate of organization strategies. Based on Freeman Model, to determine the performance rate of organization in terms of each stakeholder, 7 stakeholder groups are usually determined. Each of them has indexes for measuring the performance rate. The case study of this research is relevant to measure the performance rate of organizational strategies in MEHAR paint industry which this industrial unit produces a variety of car colors and its subsets in Iran. Findings shows the performance rate of 7 stakeholder groups includes Owners, Customers, Staff, Creditors, society, Suppliers and Government are respectively 0.749, 0.780, 0.749, 0.707, 0.749, 0.870, 0.831.

Aluminum doped ZnO sol–gel derived nanocrystals: Raman spectroscopy and solid solubility characterization

Abstract: In this study, a sol–gel method was used to synthesize Al-doped ZnO nanocrystals (AZO). For preparation of this highly concentrated sol, zinc acetate concentration was fixed at 2M. UV-visible absorption and photoluminescence spectroscopy were used to evaluate optical properties of the prepared samples. High temperature annealing was employed to evaluate the solid solubility limit of Al ions. XRD and Raman spectroscopy are then used to evaluate the doping process of aluminum in ZnO nanopowders. Disappearing of the second order Raman peak of ZnO at 1160 cm−1 was used to confirm the solid solubility limit. It can be found that the disappearing of second order Raman peak intensity at 1160 cm−1 is observed for sample with 2 at% Al3+ ion. Experimental results have shown that the solid solubility limit of aluminium ions in sol–gel derived zinc oxide nanocrystals was achieved.
