An Improved model for OKP product planning stage in a cloud-based design environment

Nowadays, in the software world, cloud computing has great importance. This massive network has reduced the cost of software for users, but has risen in revenue from manufacturers, the products of the one-of-a-kind (OKP) companies are cloud-based, and customers access the software through the cloud, In this architecture, the company places part of the software that is expensive and does not have the ability to buy for the cloud on cloud servers, and users can connect with the cloud to the cloud using this software, But since the number of users is greater than the number of servers, they must run a scheduling mechanism to execute requests, We present a timing system for OKP products in this paper, compared with two other methods, the simulation results show the superiority of the proposed method

Promoting the Quality Level of Signaling in Railway Transportation System Taking Advantage from Wireless Sensor Networks Technology

Given the importance of using the railway networks for the reliable and safe transportation of goods and passengers, which plays an important role in the economy of rail transport of the country, it is necessary to use wireless sensor network techniques to raise the quality and quantity and also maintain the application of these facilities for better control and optimal use of relevant technologies in this regard. Regarding the development of wireless sensor networks for collecting and processing environmental information, we intended to employ them in order to maintain railways, and also prevent defects that might occur in mobile machines and parts, as well as to avoid probable events and reduce human errors. Considering the limited capacity of batteries for sensor nodes in a wireless sensor network, energy efficiency is an important issue; thus mobile sinks are presented as a possible solution. In this study, the proposed routing uses Ring Routing and an optimization gravitational search algorithm for the primary selection of the ring causes an increase in a sensor network’s lifespan. In this study, by applying the proposed method in the railway transportation system, it is improved to reduce the existing errors by creating a system with a higher safety factor and high quality and efficiency, together with maximum efficiency and good speed

Evaluation of conceptual and software model in implementing enterprise resource planning (erp) with procedural approach of bpmn2 and micro service architecture

Nowadays, correct resource management of every organization depends on the integrity and relationship between suppliers, customers, stakeholders, staffs and other parties so that it is one of the main significant criteria for success of the organization. Increase in agility and flexibility within access to information is one of profits obtained from correct implementation of human resource management system managing business processes. For this purpose, this study aimed at using previous experiences to evaluate and design a new model of enterprise resource planning (ERP) using processes modeling and micro service architecture (MSA) to obtain the most effectiveness of mentioned system. This study was conducted to provide the suitable mechanism for management decision-making simplifying business processes and managing the modern knowledge relying on modern technology and applying software knowledge through automating tasks of each process in order to make relationship between intra-organizational, extra-organizational units and other informational resources based on service-oriented architecture or micro service architecture (SOA and MSA). This research can be used by organizations and manufacturing companies tending to implement ERP

Pancreatic surgery outcomes: multicentre prospective snapshot study in 67 countries

Background: Pancreatic surgery remains associated with high morbidity rates. Although postoperative mortality appears to have improved with specialization, the outcomes reported in the literature reflect the activity of highly specialized centres. The aim of this study was to evaluate the outcomes following pancreatic surgery worldwide.Methods: This was an international, prospective, multicentre, cross-sectional snapshot study of consecutive patients undergoing pancreatic operations worldwide in a 3-month interval in 2021. The primary outcome was postoperative mortality within 90 days of surgery. Multivariable logistic regression was used to explore relationships with Human Development Index (HDI) and other parameters.Results: A total of 4223 patients from 67 countries were analysed. A complication of any severity was detected in 68.7 percent of patients (2901 of 4223). Major complication rates (Clavien-Dindo grade at least IIIa) were 24, 18, and 27 percent, and mortality rates were 10, 5, and 5 per cent in low-to-middle-, high-, and very high-HDI countries respectively. The 90-day postoperative mortality rate was 5.4 per cent (229 of 4223) overall, but was significantly higher in the low-to-middle-HDI group (adjusted OR 2.88, 95 per cent c.i. 1.80 to 4.48). The overall failure-to-rescue rate was 21 percent; however, it was 41 per cent in low-to-middle-compared with 19 per cent in very high-HDI countries.Conclusion: Excess mortality in low-to-middle-HDI countries could be attributable to failure to rescue of patients from severe complications. The authors call for a collaborative response from international and regional associations of pancreatic surgeons to address management related to death from postoperative complications to tackle the global disparities in the outcomes of pancreatic surgery (NCT04652271; ISRCTN95140761)
