Harmonic navigation of multiple low-cost robotic wheelchairs in a topology of wireless sensor nodes that are deployed in a dynamic and crowded indoor environment is a Non-deterministic Polynomial-time hard (NP-hard) problem. To address this problem, we propose a distributed multi-wheelchair global harmonic navigation algorithm. The distinguishing features of the proposed navigation algorithm are global search and local conflict resolution abilities. In the proposed algorithm, a travel time prediction method adopts a penalty for potential conflicts based on wheelchairs' priority, velocity and distance between the nodes. Moreover, three harmonic rules are proposed for: 1) giving the highest priority to humans, 2) giving the highest priority to wheelchairs, 3) giving flexible priority to wheelchairs. Through extensive quantitative simulations, we explore the performance of wheelchairs in various floor plan topologies and different values for the system parameters, and demonstrate that the properties of crowded indoor environments have important influence on the performance of global navigation, such as service time. The third harmonic rule establishes the trade-off between the performance of humans and robotic wheelchairs. At the same time, physical prototype wheelchairs are implemented and they verify the proposed global harmonic navigation algorithm. Some suggestions for robotic wheelchair designers, building architects and building owners are provided based on the conclusion of the experimental results.

“…The scale of the problem of requirement analysis can be effectively reduced through obtaining service recommendation information, which means that some of the creative activities are transformed into non‐creative activities. Many methods are proposed to identify services . Step 4: Several special modules are developed immediately or published to service providers then realized by them. The analysis process of these modules ends.There may be requirements that cannot be satisfied by deployed services because of special demands and that do not resort to existing services since pursuing the high efficiency in system analysis.…”

Service-oriented paradigm presents numerous new software development patterns and idioms. Software systems are implemented by composing existing third-party services deployed in the open environment, which is significantly different from traditional software development methodologies in which systems are built through developing modules after system design in a closed environment. Therefore, it is urgent to raise a new design method to adapt to this new circumstance. We concentrate on reusing as many deployed services as possible then introduce a new life cycle model named Taiji model to illustrate this development process. The iteration-based interactive analysis method following the model is proposed to design serviceoriented systems based on the view of extracting non-creative activities from a creative activity through defining new notations or applying new rules. The method includes the interactive analysis process that analyzes requirements with deployed services in a local point of view and the iterative analysis process that redesigns system with new knowledge in a global perspective. Meanwhile, the reusable service threshold value is defined to build the uncertain candidate service set (UCSS) of each module in analysis process. The reliability and flexibility of systems can be improved through the quantitative static structure analysis on the basis of the UCSS of systems. Meanwhile, a practical dynamic service binding method that selects services according to actual states of invoking them is presented on the basis of the UCSS containing them. Finally, we also give a case study to illustrate the feasibility of this method. AN ITERATION-BASED INTERACTIVE ANALYSIS AND DESIGN METHOD 301Service-oriented computing depicts a vision that utilizes simple small-scale services as fundamental elements to construct applications that are complex large-scale services through orchestrating the simple services [2]. A loosely coupled architecture, consisted of three roles who are provider, consumer, and register, is promoted in service-oriented architecture for this scenario. The provider offers services that enable the requirement of users who can be everyone and are uncertain under the guideline of their individual experiences, domain knowledge, existing services, and specific needs. The consumer automatically requests services that are deployed on widely distributed clouds and are unknown to the consumer to satisfy the demand of functionalities, properties, personality characteristics, and runtime context then delivers new services to server the end users, other consumers, or providers. The register is designated as a mediator between the provider and the consumer, which builds knowledge to eliminate uncertainty, unknown, and randomness between them, and to construct highly dynamic, adaptable, and fault tolerance service-oriented systems through orchestrating services.Nevertheless, traditional software development models, such as waterfall model, rapid prototype model, and spiral model, are carried out in a strict ord...

“…While most experts agree that service granularity impacts service reuse, the exact mechanism for reuse of is poorly understood at present [14]. Several frameworks and layer models have been proposed for categorizing the services based on their granularity [5,[15][16][17][18].…”

This paper evaluates the promises of service reusability through an analysis of services implemented in a manufacturing enterprise. A total of 103 services implemented in the case enterprise are analyzed to understand the enablers and obstacles that have led to the reuse ratio of 13 %. The main identified enabler for reusable services was the capability to define the services as a part of reusable business concepts, which is aligned with some of the earlier studies on the adoption of service-oriented architecture in enterprises. The main reason for having overlapping services in the case enterprise was lagging migration of legacy services to use newer, reusable services. The results can be used to develop service engineering methodologies for better reusability, and the paper provides practical guidelines to help in the application of integration development efforts toward reusable services.
