Visual shape parameters and aesthetic aspects of a product are one of the crucial factors for the success of a product in the market. The type and the value of the shape parameters plays an important role in visual appearance of a product and designers tends to be critical while deciding these parameters. The aesthetic aspect of a product has been matter of concern for researchers with its electromechanical design. The Kano model has been found to be a useful tool to establish the relationship between performance criteria and customer satisfaction. To achieve the desired customer satisfaction weight of each product criteria is determined by using Kano model. This study presents an integrative design approach combining the Kano model, Taguchi method and grey relation analysis to obtain the optimal combination of shape parameters and aesthetic aspects. Prioritized criteria of aesthetic attributes have been abstracted through proposed methodology. A case study has been presented to evolve a profile of a car. © 2016 Springer Science+Business Media New York Source

Background: The objectives of the present study were phytochemical and pharmacological screening of bark of Syzygium cumini on streptozotocin (STZ)-induced diabetic Wistar albino rats. Methods: Dose selection was made on the basis of acute oral toxicity study (300-5,000 mg/kg b.w.) as per OECD guidelines. Rats were made diabetic by a single dose of STZ at 50 mg/kg b.w. intraperitoneally. The effect of Syzygium cumini extracts (500 mg/kg) on postprandial blood glucose level was determined in fasted diabetic and normal rats. Blood glucose levels were measured at 0, 30, and 90 min after the glucose administration in the OGTT study. The bark extracts were administered orally at the dose of 500 mg/kg for 21 days in the chronic study. Glibenclamide (2.5 mg/kg) was used as a standard drug for activity comparison. Statistical analyses were performed using one-way ANOVA followed by Bonferroni's multiple comparison tests. Results: The phytochemical screening showed positive results for triterpenes/steroids, glycosides, carbohydrates, alkaloids, flavonoids, saponins, tannins and amino acids. Administration of Syzygium cumini extracts 30 min before oral glucose loading significantly suppressed (p <0.001) the rise in postprandial blood glucose levels in treated rats compared to control rats but less significant than glibenclamide. Daily, continuous oral treatment of STZ-induced diabetic with various extract of Syzygium cumini for 3 weeks resulted in significant reductions in fasting blood glucose levels compared with diabetic controls. The ethanol and aqueous extracts were most active. Conclusions: This study brings out the evidence regarding phytochemistry and pharmacological activities of Syzygium cumini. Source

Viability of a product or service in the market depends upon the satisfaction that it can extend to its customers through quality. Quality function deployment (QFD) is a tool that gathers voice of customer (VoC) and inducting the expected features in the final product. It is also desirable that the practitioners of QFD must extend due importance to latent expectations of the customers, which in turn may fulfill overall customer satisfaction for a product or service. Kano et al. (J Jpn Soc Qual Control, 14:39-48, 1984; 1996) and Kano (2001) have suggested a method to identify the different categories of requirements through customer responses. Based on the QFD and Kano model analysis, a function has been proposed to adjust the traditional improvement ratio (Tan and Shen, Total Qual Manag 11:1141-1151, 2000) for each product or service attribute to recognize the importance of a attribute, which can be helpful in developing a product or service in such a manner that maximum customer satisfaction can be achieved. The proposed methodology has been illustrated using customer survey data. © 2010 Springer-Verlag London Limited. Source

Facility location decisions play a vital role in the strategic design of the global supply chain. Global supply chains are vulnerable towards different types of risks factor that causes disturbance in the allocation of certain goods at the required place and time, and with the required quality and quantity. This paper presents a model of the multi-stage global supply chain network problem incorporating a set of risk factors (such as: late shipment, exchange rates, quality problems, logistics and transportation breakdown, and production risks), their expected values and probability of their occurrence, and associated additional cost. Different scenarios are considered to demonstrate the applicability of the model. Optimal decisions regarding the facility locations and inter-echelon quantity flows in the global supply chain are based on initial information for the risk factors. Further, if any change in the expected value of risk factor has occurred, the inter-echelons shifting take place to minimize the overall cost of the supply chain. © 2011 Springer-Verlag London Limited.

The assembly line balancing problem is a non deterministic polynomial type planning problem for mass production. Layout design changes constitute a major decision that yields investment for assembly operations and numerous heuristics have been reported in the literature for solving the line balancing problems. U-shaped assembly layout offers several benefits over traditional straight-line layout in implementation of lean manufacturing and Just-In-Time technology. In the paper an attempt has been made to evaluate labor productivity in U-shaped line system and straight line system. A Critical Path Method (CPM) based approach for U-shaped assembly line has been applied for assigning the task to the work stations for assembly line layout. Results show that the CPM based U-shaped approach performs better and improve the labor productivity of assembly line layout. © 2013 Elsevier Ltd. All rights reserved. Source
