Short message services (SMS) technology, because of its high personalisation, instantaneity and convenience, can surpass traditional methods for communication. This research was carried out using the questionnaire method, and the sampling was done by the snowball method, which ensured that the respondents did receive SMS message from the public sector. It was found that the attitude of people has a significant impact on the effects of communication, especially in terms of enhancing the positive impression of the public towards the digitalisation efforts of government departments. Among the SMS receivers, 93.5% of people who successfully received the SMS opened and read the message, while 7.3% of people forwarded it. This shows that using SMS for sending information has the effect of informing the public. However, the public sector must find ways to further encourage people to forward the information. In addition, this research found that sending policy announcements through SMS at 10am yielded the best results, while 3pm proved to be the best time to send tourism-related information. Therefore, we conclude that sending the right kind of information at the right time can contribute to raising the public's satisfaction towards government departments.

Nowadays, in order to achieve advantages in supply chain management, how to keep inventory in adequate level and how to enhance customer service level are two critical practices for decision makers. Generally, uncertain lead time and defective products have much to do with inventory and service level. Therefore, this study mainly aims at developing a multiechelon integrated just-in-time inventory model with uncertain lead time and imperfect quality to enhance the benefits of the logistics model. In addition, the Ant Colony Algorithm (ACA) is established to determine the optimal solutions. Moreover, based on our proposed model and analysis, the ACA is more efficient than Particle Swarm Optimization (PSO) and Lingo in SMEIJI model. An example is provided in this study to illustrate how production run and defective rate have an effect on system costs. Finally, the results of our research could provide some managerial insights which support decision makers in real-world operations.

Abstract. When the citizens of Hsichu became concerned about their polluted atmosphere their thoughts centered on their mode of transportation. An investigation by the city government resulted in a study which showed that if more people rode buses for working, shopping, etc. this result would be fewer cars and scooters on the streets. In order for this to come about, the bus service needed to be improved. The SWOT model was implemented. SWOT stands for Strengths, Weaknesses, Opportunities and Threats.
