Business process modeling with cloud computing support

Precise and clear Business Process Modeling (BPM) can be used to implement the all of processes according to the user’s needs. On the other hand, cloud computing has become a solution for data storage and more effective and efficient computing processes. State Polytechnic of Malang (Polinema) is one of the vocational higher education Institutions in Indonesia that requires business process modeling to facilitate an integrated understanding of process flow. This study aims to describe the business processes of the financial realization system and the structure of cloud computing that can be used. This research used Bizagi for designing Business Process Model and Notation (BPMN) in modeling business processes of financial system realization. This paper describes the business model of the financial realization system at Polinema. This study proposes the use of an Infrastructure as a Service IaaS-based cloud computing service model using a hybrid cloud approach to support the work of the system.

The Effect of Thickness-Based Dynamic Matching Mechanism on a Hyperledger Fabric-Based TimeBank System

In a community with an aging population, helping each other is a must society function. Lacking mutual trust makes the need for a fair and transparent service exchange platform on top of the public service administration’s list. We present an efficient blockchain-based TimeBank realization with a newly proposed dynamic service matching algorithm (DSMA) in this work. The Hyperledger Fabric (or Fabric in short), one of the well-known Consortium Blockchains, is chosen as our system realization platform. It provides the identity certification mechanism and has an extendable network structure. The performance of a DSMA is measured by the waiting time for a service to get a match, called the service-matching waiting time (SMWT). In our DSMA, the decision as to whether a service is to get a match or wait for a later chance depends dynamically on the total number of contemporarily available services (i.e., the thickness of the service market). To better the proposed TimeBank system’s service quality, a Dynamic Tuning Strategy (DTS) is designed to thicken the market size. Experimental results show that a thicker market makes on-chain nodes have more links, and in turn, they find a match easier (i.e., consume a shorter SMWT).

Construction and system realization of the yarn tension model of fully fashioned flat knitting fabric

In recent years, fully fashioned flat knitting fabrics have been extensively studied owing to their superior formability, rich application range and advanced knitting technology. However, the yarn tension fluctuations during the knitting process are difficult to control. The yarn tension in the knitting process is affected by many factors, such as the carriage running speed, structure, yarn properties, clothing parameters, and so on. In this work, a tension model of the yarn was established to explore the regularity of yarn tension variation, which was caused by the running speed and direction of the carriage when producing fully fashioned fabrics. Then, a tension compensation device was set up to reduce tension fluctuations to improve the quality of fully fashioned fabrics. Results showed that the tension fluctuation in the dynamic change of the tension was reduced to a certain extent by adding the tension compensation device. Meanwhile, the average value and fluctuating standard deviation of the yarn tension between the forward and backward processes were significantly reduced during a cycle of the knitting process. This indicates that controlling the tension fluctuation in the knitting process will effectively improve the surface evenness of the fully fashioned flat knitting fabric.
