This paper brings up this idea of using Near Field Communication (NFC) for inventory control system instead of using traditional barcodes. NFC because of its high security, ease of use and efficiency can be very suitable for systems like inventory control. In traditional inventory control systems, each product has a barcode pasted on it, which is vulnerable to attacks as barcodes are open and have no security. Furthermore, barcodes are prone to damages and can be unreliable when pasted on different types of products e.g. hot and frozen products, circular shaped products and irregular shaped products like clothes etc. NFC on the other hand is very efficient, secure and reliable when it comes to short-range wireless communication. In this paper we will present our prototype for the inventory control system of an electronic store in which each product has a passive NFC tag pasted to it. When a customer buys a product the receipt of the product is generated using NFC between the NFC passive tag on the product and NFC enabled device (e.g. smart phone or reader) at the cash counter.

Desirable Feature

As various ubiquitous computing technologies become applied into many smart space systems, most museums attempt to use these techniques for their own domain. Near Field Communication(NFC) is one of wireless technologies primarily used for short range communication between smart phones and similar devices, supporting a variety of information exchange services in some effective way. In this paper, we present a new user similarity-based contents recommendation service to improve the counterpart of our previously developed museum viewing system by using NFC. In order to satisfy this goal, this service utilizes similarity of artifact attached NFC tagging patterns of users. Its desirable feature enables users to actually find and obtain their favorite contents by systematically consulting the tastes of the other users very close to those of the first. Also, the proposed system may considerably reduce overloading on contents providing servers by having smart phone clients get certain parts of basic artifact related contents information directly through NFC tags, not the servers.

Production Inventory

Purpose This paper aims to optimise the dynamic performance of production–inventory control systems in terms of minimisation variance ratio between the order rate and the consumption, and minimisation the integral of absolute error between the actual and the target level of inventory by incorporating the Pareto optimality into particle swarm optimisation (PSO). Design/method/approach The production–inventory control system is modelled and optimised via control theory and simulations. The dynamics of a production–inventory control system are modelled through continuous time differential equations and Laplace transformations. The simulation design is conducted by using the state–space model of the system. The results of multi-objective particle swarm optimisation (MOPSO) are compared with published results obtained from weighted genetic algorithm (WGA) optimisation. Findings The results obtained from the MOPSO optimisation process ensure that the performance is systematically better than the WGA in terms of reducing the order variability (bullwhip effect) and improving the inventory responsiveness (customer service level) under the same operational conditions. Research limitations/implications This research is limited to optimising the dynamics of a single product, single-retailer single-manufacturer process with zero desired inventory level. Originality/value PSO is widely used and popular in many industrial applications. This research shows a unique application of PSO in optimising the dynamic performance of production–inventory control systems.

Nowadays people especially those in the metropolitan area or developing their livelihood on a smart phone. Based on this, there arose an idea to expand and enrich the smart phone functions not only as a medium of communication, but one of them as a device that can help people in carrying out daily activities. One of them as a device that can help people to supplement the existing weaknesses in him, such forgetfulness. Forgetting the parking location is one of human weakness because of forgetfulness. That requires a device that can help people to remember the location of parking their vehicles. In addition, the smart phone also can help people to make payment transactions more practical. Then, if a parking location reminder device combined with payment at the parking booth will be a very useful tool and efficient. With smart phone technology is increasingly sophisticated and technology support NFC (Near Field Communication) device is expected to be a solution to deal with problems that often occur in parking location and minimize queuing at the ticket counter payment of parking

Emerging commercialised anthropomorphic hand prostheses have two main categories: expensive ones with remarkable functionality afforded by complex control systems, and inherently inexpensive ones with basic gripper-like aptitudes that do not fully fulfil the basic physical and emotional requirements of upper-limb amputees or individuals with upper limb congenital defects. This paper aims to establish a middle ground between these two commercial alternatives by realizing a low-cost and highly functional robotic hand. All five digits of the proposed robotic hand are controlled by a single DC motor. This desirable feature is afforded by the implementation of under-actuation. The under-actuation in the fingers is achieved through four-bar linkages coupling with cartwheel flexure joints, which leads to not only shape adaptation, i.e., the ability to naturally adapt to the form of the article being grasped without the aid of intricate control systems, but also low cost due to the possibility of monolithic fabrication (e.g. 3D printing) and ease of control. The under-actuation in the palm system is implemented via the use of a differential pulley mechanism embedded thereof, which furthermore results in low cost by reducing the number of actuators and simplifying the control system. A simple and easy-to-use control system based on voice commands through a smart phone was also developed. It is envisaged that the proposed design can also be applied in various engineering environments to meet adaptability/under-actuation needs.

Abstract This paper looks at the heavy-haul combined train composed of different types of locomotives and its distributed power control system with a combination of 800 MHz and TD-LTE wireless communication. It analyses some key characteristic parameters that affect the synchronism and communication of the differential wireless multi-traction synchronous control systems for heavy-haul combined trains. At the same time, in order to reduce the latency of instruction and information transfer between different types of locomotives, improve the time-limit certainty of wireless transmission and optimize the control quality of multi-traction control systems for heavy-haul combined trains, a synchronism optimization strategy based on the Markov decision process on the basis of Petri networkconstruction is proposed. Relevant experiments and tests are carried out to verify the effectiveness of the synchronism optimization of the control system, which provides a guarantee for improving the differential wireless multi-traction synchronous control system for combined trains and optimizing train control.

The Impact

The aim of this paper is to examine the beneficial impact of feedback information in the dynamics of production-inventory control systems. Two production-inventory control system models are analyzed: APIOBPCS and 2APIOBPCS models. The simulation-based experiment designs were conducted by using the state-space equations of the two models. The bullwhip effect as measured by the variance ratio between the order rate and the consumption rate, and inventory responsiveness as measured by the Integral of Absolute Error between the actual and the target levels of inventory, are two metrics used to evaluate the performance of the production-inventory control system in response to a random customer demand. To ensure that both models work under optimal performance, multi-objective particle swarm optimization (MOPSO) is employed to address the problem of tuning the controller’s parameters. The simulation results show the 2APIOBPCS model outperforms the APIOBPCS model at achieving the desired bullwhip effect and being able to provide better inventory responsiveness. The improvement in the inventory responsiveness becomes more significant when the system operates under mismatched lead time and/or an initial condition.
