This study proposes a systematic process in the pre-startup stage of establishing independent and franchised catering micro businesses. A questionnaire based on the key success factors (KSFs) affecting the establishment of a micro business was developed. Grey relational analysis (GRA) was performed to determine KSFs that can affect the start of a catering micro business, while interpretive structure modelling (ISM) was used to establish the pre-startup process. Studies show that GRA and ISM results were different in the two types of catering businesses. Therefore, business starters ought to investigate their industry of interest and determine the startup process prior to establishing their respective businesses.

We study a replenishment model that the retailer shares his leftovers on his direct online sales channel and traditional retail channel. When one of the sales channels is out of stock and another has leftovers, the latter shares its leftovers with the former. Commonly, there is competition between two channels. Therefore, we take the consumers' behavior including retailer inconvenience cost of traditional retail channel, and risks and delivery lead time of direct online sales channel into consideration. Then, we use the function of consumer utility to measure the Demand distribution function. Furthermore, the optimal replenishment models in independent decision-making and in lateral transshipment are established separately. Then the results of two models are compared by order quantity and retailer's profit. What's more, it is found that lateral transshipment between dual sales channel inventory can reduce the order quantity and increase the retailer's profit when the prices and demand distribution satisfy certain conditions. Finally, the numerical analysis of the model is carried out. The validity of the research results is proved by examples.
