Research paper thumbnail of A Fuzzy Economic Order Quantity (EOQ) Model with Consideration of Quality Items, Inspection Errors and Sales Return

The screening process to remove the defective items may involve two types of errors. In this article we extend the Khan et al. (2011) model by considering demand and defective rate in fuzzy sense and also sales return in our model. The objective is to determine the optimal order lot size to maximize the total profit. We use the signed distance, a ranking method for fuzzy numbers, to find the approximate of total profit per unit time in the fuzzy sense. The impact of fuzziness of fraction of defectives and demand rate on optimal solution is showed by numerical example.

This technology can be used as an effective tool to create interactions between firms and customers. The purpose of this research is to reveal the importance of satisfaction and immersion in social media brand interactions and the creation of customer value. This study is considered as an applied, empirical and descriptive research study. The results show that satisfaction and immersion through social media interactions create customer value for brands. Both interaction satisfaction and interaction immersion have positive effects on customer value creation (CLV, CIV and CKV). The findings of this study show the importance of setting social media platforms for brands to maximise the customer and firm interactions. The more the firms increase their social media activities and interactions, the better customer value they get.
