    Procurement of goods in Indonesia continues to experience rapid growth. In 2022, the Indonesian government has allocated a budget of Rp. 2,714 trillion to fulfill government spending. Procurement of goods is almost carried out every month, to meet office needs and support operational facilities. Document storage is one of the important things in every company, however, until now there is no mobile application that can help archiving documents online. This is a problem where files are created and stored manually, so it is still difficult to find files and in transparating data. From the existing problems, there needs to be an innovation that can facilitate the process of managing and storing matching files. One of the innovations was carried out by designing a mobile application using the Design Thinking method. The Design Thinking method can be used to solve problems by rearranging problems into user perspectives that produce design ideas. The results of this study are in the form of a procurement mobile application design. It is hoped that the design and development of the mobile application will be able to provide convenience for Company XYZ in storing procurement documents. So that procurement can be done appropriately, effectively, efficiently, and the procurement documentation process can be carried out quickly

    International Workshop on Middleware for Pervasive and Ad-hoc Computing MPAC 2003), ACM/IFIP/USENIX International Middleware Conference (Middleware 2003), Rio de Janeiro, Brazil This work was supported by the FP5 Gloss project IST2000-26070, with partners at Trinity College Dublin and Université Joseph Fourier, and by EPSRC grants GR/M78403/GR/M76225, Supporting Internet Computation in Arbitrary Geographical Locations, and GR/R45154, Bulk Storage of XML Documents.Pervasive services may be defined as services that are available "to any client (anytime, anywhere)". Here we focus on the software and network infrastructure required to support pervasive contextual services operating over a wide area. One of the key requirements is a matching service capable of as-similating and filtering information from various sources and determining matches relevant to those services. We consider some of the challenges in engineering a globally distributed matching service that is scalable, manageable, and able to evolve incrementally as usage patterns, data formats, services, network topologies and deployment technologies change. We outline an approach based on the use of a peer-to-peer architecture to distribute user events and data, and to support the deployment and evolution of the infrastructure itself.Peer reviewe

    An Introduction to Pervasive Interface Automata

    Pervasive systems are often context-dependent, component based systems in which components expose interfaces and offer one or more services. These systems may evolve in unpredictable ways, often through component replacement. We present pervasive interface automata as a formalism for modelling components and their composition. Pervasive interface automata are based on the interface automata of Henzinger et al, with several significant differences. We expand their notion of input and output actions to combinations of input, output actions, and callable methods and method calls. Whereas interfaces automata have a refinement relation, we argue the crucial relation in pervasive systems is component replacement, which must include consideration of the services offered by a component and assumptions about the environment. We illustrate pervasive interface autmotata and component replacement with a small case study of a pervasive application for sports predictions
