The construction of a mobile business application system for ERP

Abstract

Purpose – In today’s complicated and competitive business environment, companies commonly use enterprise resource planning (ERP) systems to integrate management information and enhance efficiency. In recent years, due to the development of cloud computing and portable devices, a new mobility era is starting. The popularity of smartphones and tablet computers has changed the behavior of mobile-phone users and enhanced the rapid development of mobile commerce. ERP companies have discovered this trend and want to provide more convenient services and develop more integrated functions for their ERP systems in which practitioners can operate and access company information through various mobile devices anywhere, anytime. However, mobile ERP is still in the development stage. On the whole there has been relatively little research into the framework and system implementation of mobile ERP until recently. The purpose of this paper is to propose a mobile ERP framework for the sales function in an ERP system. The authors also design a mobile type sales application based on an android-based mobile device. In addition, the authors provide sale practitioners and supervisors with a more convenient and rapider service interface in which they can quickly respond to customers’ needs. Design/methodology/approach – The authors develop a mobile ERP framework taking into account the requirements of sales and distribution modules. The proposed framework can directly access the ERP system and perform more efficiently than a web service-based framework since middleware services are not involved. Findings – For the purposes of demonstrating the efficiency of the proposed mobile ERP system, the authors examine three scenarios which are commonly used in world-wide integrated circuit (IC) design companies. In this kind of company, salespersons travel to various cities and collect sales information. The three various scenarios include: (A) sales order creation; (B) order status inquiry; (C) order modification. The results of simulation show that the mobile ERP system indeed enhances the efficiency of processing operations in sales and distribution modules, particularly for salespersons visiting outside offices and traveling world-wide. Research limitations/implications – The authors investigate and propose a mobile ERP framework for a world-wide ERP system company, SAP, which is a research limitation in the paper, since SAP ERP system is not installed for all companies. In addition, from this investigation, two possible concerns might be useful in further research. The first involves other modules may be included in the proposed mobile ERP framework. The second is the need to integrate other useful analysis systems, such as business intelligence, for a more complete mobile ERP system. Practical implications – To demonstrate the efficiency of the proposed mobile ERP system, three various scenarios which are commonly used in world-wide IC design companies are considered. In addition, the comparisons of the typical procedures in terms of average processing time for existing ERP systems and the proposed mobile ERP system are provided. The simulation times finding show that the mobile ERP system indeed enhances the efficiency of processing operations in sales and distribution modules, particularly for the salespersons visiting outside offices and traveling world-wide. Social implications – The popularity of smartphones and tablet computers has changed the behavior of mobile-phone users and enhanced the rapid development of mobile commerce. Mobile ERP systems can provide more up-to-date information than typical ERP systems involving order-tracking, real-time stock quantity checking, and sales order creations since salespersons still can access or update their collected information wherever they are world-wide. The contributions of this paper have a great impact on behavior changes of mobile-phone users. It can enhance efficiency and quality of life for users. Originality/value – In the paper, the authors propose a mobile ERP framework for the sales function which can provide sale practitioners and supervisors a more convenient and rapider service interface in which they can quickly respond to customers’ needs. The proposed framework of mobile ERP perform more efficiently than typical ERP systems and a web service-based framework since middleware services are not involved.

Consumer attitudes toward online video advertisement: YouTube as a platform

“…Our study shows that the proposed model explained most of the variance in terms of attitude toward advertisements on sites providing online video services, such as YouTube. The results indicate that the model's appropriateness in the situation of online video advertising is confirmed by the degree to which the findings are in accordance with those of previous investigations in different areas, such as internet advertisements (Brackett and Carr, 2001) and mobile advertisements (Tsang et al , 2004, Tai et al , 2016).…”

Bangladeshi ready‐made garment development via ubiquitous and mobile computing

“…We have several offices and currently we coordinate by physically visiting the offices.In this scenario, one general manager (RMGGM1) suggested how MbUS could assist in improving coordination:

If MbUS is implemented (in my factory), all employees will be connected to the system and I can coordinate jobs without visiting them.

The impact of improved coordination was also reported by Rathore and Ilavarasan (2014) who noted better communication improved coordination in supply chains. A study by Tai et al (2016) also suggested construction of a mobile business application system for ERP improved the selling process in an enterprise. The latest mobile phones are equipped with a myriad of sensors, cameras, and microphones; these features of mobile phones can also assist RMGs offer location‐aware services, improving the supply chain, reducing process loss, and helping with inventory management.…”

Construction of Mobile Screening Movie Recommendation Model Based on Artificial Immune Algorithm

“…ere are generally two types of data involved in the recommendation system, namely, scoring data and single-type data. e single-type data contains only 0 and 1 data, and the scoring data is distributed in a certain scoring interval, such as the scoring interval of [1,5]. When the recommendation algorithm solves a single-class problem, the following problems need to be considered: first, the problem of sparseness, that is, there is little information related to user selection.…”

“…ere are many applications in this area [4]. Companies such as Baidu and Taobao use information such as user search history and cookies generated by visiting websites to calculate the advertisements that each user may be interested in [5]. e video website provides recommendations to users based on the cookie information of the user's browsing.…”
