Applying the Technology Acceptance Model (TAM) in Information Technology System to Evaluate the Adoption of Decision Support System

With the beginning of the information systems’ spreading, people started thinking about using them for making business decisions. Computer technology solutions, such as the Decision Support System, make the decision-making process less complex and simpler for problem-solving. In order to make a high-quality business decision, managers need to have a great deal of appropriate information. Nonetheless, this complicates the process of making appropriate decisions. In a situation like that, the possibility of using DSS is quite logical. The aim of this paper is to find out the intended use of DSS for medium and large business organizations in USA by applying the Technology Acceptance Model (TAM). Different models were developed in order to understand and predict the use of information systems, but the information systems community mostly used TAM to ensure this issue. The purpose of the research model is to determine the elements of analysis that contribute to these results. The sample for the research consisted of the target group that was supposed to have completed an online questionnaire about the manager’s use of DSS in medium and large American companies. The information obtained from the questionnaires was analyzed through the SPSS statistical software. The research has indicated that, this is primarily used due to a significant level of Perceived usefulness and For the Perceived ease of use.

Effects of Information Technologies Over Decision-Making Process About Cost Controlling at Food and Beverage Departments at Five-Star Hotels

Information technologies play an important role in many business areas. One of these areas is hotel information system. Many operations, such as check-in, check-out, and food and beverage, are performed owing to information technologies. Package programs are used for managing hotel operations. Software provides reporting, filtering, remote accessing, and cost control services which are important key parameters of decision-making processes of hotel managers. Cost control is one of the most important operations in hotel management. Cost control service of package programs assists managers in monitoring overall cost and computing each department＇s partial cost and serves information to the different departments of hotels using information technologies. Cost control is important in the departments which are profitable in a hotel. Food and beverage is one of these profitable departments, which is the second profitable department in hotels. It makes profit between mostly 20% and 40%. This research aims to understand effects of information technologies during decision-making processes. The sample of study is food and beverage managers in five-star hotels in Istanbul. Questionnaire was applied to 45 participants.

A multi-user decision support system for online city bus tour planning

Tourism is rapidly becoming a sustainable pathway toward economic prosperity for host countries and communities. Recent advances in information and communications technology, the smartphone, the Internet and Wi-Fi have given a boost to the tourism industry. The city bus tour （CBT） service is one of the most successful businesses in the tourism industry. However, there exists no smart decision support system determining the most efficient way to plan the itinerary of a CBT. In this research, we report on the ongoing development of a mobile application （app） and a website for tourists, hoteliers and travel agents to connect with city bus operators and book/purchase the best CBT both in terms of cost and time. Firstly, the CBT problem is formulated as an asymmetric sequential three-stage arc routing problem. All places of interest （PoI） and pickup/dropout points are identified with arcs of the network （instead of nodes）, each of which can be visited at least once （instead of exactly once）. Secondly, the resulting pure integer programming （IP） problem is solved using a leading optimization soft- ware known as General Algebraic Modeling System （GAMS）. The GAMS code developed for this project returns： （1） the exact optimal solution identifying the footprints of the city bus relative to all the arcs forming the minimal cost network; （2） the augmenting paths corre- sponding to the pickup stage, the PoI visiting stage and the drop-off stage. Finally, we demonstrate the applicability of the mobile app/website via a pilot study in the city of Melbourne （Australia）. All the computations relative to the initial tests show that the ability of the app to answer users＇ inquiries in a fraction of a minute.

IT Project Evaluation and Investment Decision

There are many kinds of real options,which are valuable,in each phase of the lifetime of an information technology(IT)project.However,in the current IT investment decision theory,real options that embedded in IT projects are not considered. In this paper, the process of IT project decision and implementation is fully analyzed, the real options that may be embedded in an IT project are identified, and a real option analysis (ROA) method is proposed for evaluation of an IT project under uncertain business environment. ROA employs Black-Scholes expansion model and cancels the assumption that the cost of project is certain. The numerical example manifests that the ROA can better evaluate IT project and select the IT investment alternative. Finally, a road map is provided to help selecting the suitable evaluation method to make IT investment decision.

基于地理信息技术和模糊层次分析-模糊决策试行与评价实验方法(AHP-DEMATEL)的区域大型光伏电站选址指标体系构建:以内蒙古为例

以往关于大型光伏电站选址研究中,采用层次分析(AHP)方法的指标间相互独立,指标权重还有改进空间,同时指标间存在一定的交叉和冗余,为此,通过对在不同自然、社会条件地区建设大型光伏电站选址研究的指标进行对比和筛选,研究区域大型光伏发电站建设选址的典型指标体系。考虑到人工成本和民众接受度在区域大型光伏发电站项目建设中的重要影响,在已有主要指标基础上增设上述两个指标,构建包括资源、环境、经济、社会4个维度的区域大型光伏发电站选址评价指标体系,并以内蒙古为例,在地理信息技术(GIS)环境中采用AHP与决策试行与评价实验法(DEMATEL)对所获取的数据进行归一化处理,对有关指标赋权,从而绘制区域大型光伏发电站建设的空间适宜性分布地图,实现可视化数据分析。在综合考虑辐射强度、日照时间、坡度以及经济水平等因素后得出,选址在内蒙古西南部的适宜度高于东北部,其中最适宜地区位于巴丹吉林、腾格里、乌兰布和沙漠及毛乌素沙地;而腾格里沙漠西侧及巴丹吉林沙漠等地基础设施建设薄弱、交通不便,应稍后发展。研究结果与内蒙古已建成的大型集中式光伏发电站分布情况相符,模型的可靠性得以验证。

数字化转型对企业技术并购决策的影响研究

在数字经济快速发展的背景下,数字化转型成为推动企业高质量发展的关键战略方向。本文基于文本分析的方法依据上市公司年度报告相关信息来测量企业数字化转型水平,并使用2007~2018年上市公司并购数据,研究数字化转型对企业技术并购决策的影响及其作用机制。研究发现:数字化转型显著提高了企业发起技术并购的概率、频率和规模,并且在一系列稳健性检验后该因果关系仍然成立。机制分析表明,企业数字化转型程度的提高,有效改善企业信息不对称程度以及提高公司治理能力,进而助推企业发起技术并购。同时,信息不对称程度越低和公司治理能力越高的企业,在完成一次技术并购项目后,会倾向于再次发起技术并购,技术并购绩效也会更好。数字化转型对企业技术并购的影响具有明显的异质性,在数字经济发展较好地区的企业和非国有企业中促进效果更加显著。本文研究为企业数字化转型经济后果和技术并购影响因素的研究做出重要补充,为相关政策制定以驱动数字经济发展提供了启示。
