The provisions of the European law have defined “Smart Metering” as a tool for remote meter readings and management of energy networks. Currently, after years of research and many real- life applications, it is one of the most popular solutions that defines friendly and modern cities. Similarly to automatic street lights, traffic signals or waste management systems, monitoring and control of water supply and sewage systems significantly improves the quality and comfort of life of city residents. The city infrastructure managers may use it as a tool that primarily allows for some cost savings and better resource management. The paper describes a remote transfer of water meters data through the Internet of Things technology. Also additional options have been presented, which are available once the data on water demand has been acquired. They can be communicated to other clients, e.g. other municipal services, as an element of Smart City, and to the customers. Thanks to this technology, the customers may analyze and better manage their actual water consumption trying to optimize it. Over time, it seems that saving water has become not only a fashionable whim but a trend to stay.

Machines are valuable assets that need to be protected from damage and failure through proper maintenance measures. This paper proposes a system that automatically monitors the running time of machines and sends notifications regarding their preventive maintenance (PM) schedules. The system core consists of a programmable logic controller (PLC) and a human machine interface (HMI). The HMI is connected to an online platform via internet connection provided by a router, so that the monitoring result can be accessed via Android smartphone or laptop/PC. This IoT-based running time monitoring system (IRTMS) will be particularly helpful in implementation at an production site that consists of multiple various machines. The PM items of a machine may vary from cleaning, changing single component, to an overhaul, each with different time interval. By using the IRTMS, the user will have an overview of the PM schedules anytime and anywhere. The preparation of material, components, or tools can be known ahead of time. For simulation purpose, a prototype is constructed by using components as used in industrial real-life condition. Four output connections are provided to simulate the simultaneous monitoring of four machines. The IRTMS prototype is tested and completely successful on doing the running time monitoring, the running time reset, the PM notifications, and the remote access for monitoring and control.

Water is a necessity that is so important for every creature in the world, and the estimate of water must always be available or it is in homes, offices, public places or industry. This causes the water storage tank to play an important role in ensuring the availability of air is always there and under control. In this research, it is based on an Android-based Water Pump Monitoring and Control system with the support of IoT (Internet of Things) technology so that it makes it easier for users to monitor the amount of water in the storage tank and control the water pump to fill water into the tank, the system built is supported by the NodeMCU module. esp8266, Relay and Ultrasonic Sensor and connected to the Blynk application which functions as an application interface in monitoring and controlling the water pump. If the air has determined the specified distance, a notification will appear to immediately turn off the water pump, thus it is hoped that this system can help users see the condition of the water pump and water tank even though they are not at home

Planning Problems

In order to gain competitive advantage in the globalization today, effective management strategies need to be incorporated, especially in collaborating information sharing among multi-site manufacturing facilities. Information visibility within the supply chain is the process of sharing critical data required to manage the flow of products, services, and information in real time between suppliers and customers. If the information is available but cannot be accessed by the parties most able to react to a given situation, its value degrades drastically. We propose a software system, which incorporates mathematical models, user-interface and web application to solve the collaborative planning problems between multiple sites. Model validations proved the architecture to be robust and suggested cost savings through priority goal structuring. This paper offers a practical solution to real-life industrial problems often faced by the management of manufacturing industry in the world today.

In fairy tales and traditional romance movies, the story ended when the prince found his soul mate, married her, and rode off with her into the sunset. The ending caption said: “They lived happily ever after.” Well, we know that real life is not quite that simple; after the marriage comes the most difficult (and, one hopes, interesting) part. Similarly, a great project contract and plan is of little consequence without constant monitoring and control. Once the project is planned and underway, the project manager cannot simply ride away and assume that everything will go according to plan. To insure success, many project matters need to be monitored; if a matter deviates from the plan, then some form of control must be exerted to bring the situation back in line with the plan. In this chapter I discuss the many matters that need to be monitored for IT projects, how best to monitor each matter, and what type of control actions may be appropriate for each.

Over the past few years, there has been a growing awareness regarding the concept of Internet of Things (IoT), which involves connecting to the Internet various objects surrounding us in everyday life. The main purpose of this concept closely connected to the smart city issue is increasing the quality of life by contributing to streamlining resource consumption and protecting the environment. The LoRa communication mechanism is a physical layer of the LoRaWAN protocol, defined by the LoRa Alliance. Compared to other existing technologies, LoRa is a modulation technique enabling the transfer of information over a range of tens of kilometers. The main contribution this paper brings to the field is analyzing the scalability of the LoRa technology and determining the maximum number of sensors which can be integrated into this type of monitoring and control architecture. The sensor architecture is specific to the smart city concept that involves the integration of a large number of high-density sensors distributed on a large-scale geographic area. The reason behind this study is the need to assess the scalability of the LoRa technology, taking into consideration other factors, such as the packet payload size, the duty circle parameter, the spreading factor, and the number of nodes. The experimental results reveal that the maximum number of LoRa sensors that can communicate on the same channel is 1,500; furthermore, in order to obtain a high performance level, it is necessary to schedule and plan the network as carefully as possible. The spreading factor must be allocated according to the distance at which the sensor is placed from the gateway.

Abstract Background To conduct a pilot study on an alternative model for the provision of respiratory therapies in sleep apnea-hypopnea syndrome (SAHS) by internalizing the service with the purchase, monitoring and control of continuous positive airway pressure (CPAP) equipment by the hospital. Methods An observational, prospective pilot study of comparative cost analysis by internalizing the service to include all patients up to a budget limit of 5000 euros. The cost of internalizing the service included the acquisition of CPAP equipment and all the necessary accessories in addition to the nursing days necessary to track the patients. Patient satisfaction was assessed by a survey of the hospital service. Results Twenty-one patients with 23,046 patient-days of follow-up were included. The cost of the internalized system was 6825.11 €. The cost of the outsourced system over the same period would have been 22,781.18 €; thus, the direct saving was 15,956.07 €. The cost per device per day of the internalized system was 0.30 € versus the 0.99 € that the outsourced system would have cost during the study period. In the satisfaction survey, 12 (70.6%) patients indicated that they preferred the service of the hospital over that of the external company. No patient preferred the outsourced system. Conclusions The internalization of CPAP service represents significant cost savings from a hospital perspective and an improvement in patients’ perceptions of the quality of service.

The closely combination of Internet of Things and on-site monitoring and control technology is the development tendency of the site monitoring and control technology, especially the special equipment safety monitoring technology. EDGE technology is one way of Internet of Things technology realization. EDGE technology is a digital mobile phone technology which allows improved data transmission rates as a backward-compatible extension of GSM. It is also considered as a pre-3G (2.75G) radio technology and is part of ITU's 3G definition. It is used as one of the aims of the project which allows the operators to keep abreast of the crane operation status. Then a software platform is developed to monitor the real-time stress. A software platform is developed via a lot of preliminary work as mentioned above. The information is collected by FBG sensors and transmitted to the demodulator, and then the software calculates strain by a formula given in. Finally we acquire the real-time stress in different parts of the crane. If the real-time stress exceeds the allowable stress, it issues an alarm signal to the operator.
