Abstract

This research applies the cuckoo search metaheuristics model to find solutions to the Orienteering Problem (OP). The OP formulation is useful to model a situation in which someone wants to determine an optimal city route that is subject to a specified time constraint. OP can be categorized into NP Hard Problem which takes a very long time to analytically find the optimal solution as the number of entities involved increases. Therefore, metaheuristics often become an option to deal with this situation. A cuckoo search model based algorithm is developed in this research. An adjustment for discrete combinatorial problem is performed by adopting an idea of binary cuckoo search method. In addition, three types of local search methods are considered to improve the searching performance. This algorithm can eventually find better solutions for some of the 18 cases than two other benchmarked algorithms. Furthermore, experiment on model parameters shows that the worse nest fraction (P_alpha) affects the quality of solutions obtained.

Abstract

This research explores some potential factors that affect the continuance intention of a mobile payment service. The trend of mobile payment services has been increasing since the last few years. The advancing technology of the internet and smartphone has been a supporting environment for the growth of this method. Many similar mobile payment services are offered in the community which results in a highly competitive business condition. The business owner who has put a high investment in this business will surely want to keep it running and even grow their product. Therefore, some knowledge of factors that can significantly promote the sustained use of their product to customers will be imperative. In this research, some existing models on the general repurchase intention concept and users’ continuance intention will be combined and tested to figure out some influential aspects to continuance intention concept. Seven factors are hypothesized to have direct and indirect effects. Data from 193 respondents are gathered and the results of the tested model shows perceived quality, perceived value, and brand preference subsequently influence the continuance intention. Further analysis is also conducted in this research to explain the relationship between factors as well as analysis of current mobile payment providers.
