ORGANIZATION OF CUSTOMER INTEGRATED SERVICE SUPPLY CHAINS – IPS²-EXECUTION SYSTEM (IPS²-ES) FOR PLANNING AND SCHEDULING THE SERVICE DELIVERY FRIEDRICH MORLOCK & THOMAS DORKA I. ABSTRACT Industrial Product-Service Systems (IPS²) are a new way to deliver customer value in contrast to just offering a product and providing services. The delivery of IPS² is performed with a network that includes suppliers as well as the IPS² provider and the IPS² customers. To support the IPS² provider in the management of this network and the planning of the required resources for the IPS² delivery, a software tool is required. The development of such a system is the aim of the research project. Therefore, an IPS²Execution System is introduced and designed. For the implementation of the IPS²-ES requirements for the IPS² delivery have to be collected. Based on that, a system architecture can be developed and a prototype of an IPS²-ES can be implemented. Due to the complexity of the automatic planning and control of the IPS²-ES, the output of the system cannot be manually controlled. Hence, an automated method to measure and rate the resulting IPS² focused on the planning algorithm and IPS² network has to be developed.

to enable the delivery of processes that are needed to cover unplanned demands that arise on short notice. Strategic capacity planning influences which partners are composed to which IPS² network and defines the planned IPS² delivery network, operational resource planning changes the IPS² delivery networks to cover all demands. Both use a genetic algorithm to generate delivery plans. [5]

II. INDUSTRIAL PRODUCT-SERVICE SYSTEMS (IPS²) In the manufacturing industry competitors are continuously struggling to differentiate from other companies in the market. Industrial ProductService Systems (IPS²) offer this differentiation by representing a paradigm shift from traditional product selling and service offering to providing customer value, as presented by [1]. [1] also presents the following definition of IPS² based on [2]: “An Industrial Product-Service System is characterized by the integrated and mutually determined planning, development, provision and use of product and service shares including its immanent software components in Businessto-Business applications and represents a knowledge-intensive socio-technical system.” According to [3], the IPS² Lifecycle is divided into five phases: planning, development, implementation, delivery and use as well as closure. The research presented in this paper is focused on the delivery and use phase of IPS². To support the IPS² provider during this phase an IPS²Execution System (IPS²-ES) is needed for planning, scheduling and organization of the required delivery processes and the partner network.

V. PERFORMANCE MEASUREMENT (Morlock) Elements of the IPS²-Execution System like planning and IPS²organization are automatically executed. Thus it is difficult to measure and evaluate these elements manually. To measure and evaluate organizational and planning issues a Performance Measurement Method (PMM) to support the IPS²-provider is needed. The Performance Measurement Method measures the IPS²-network and –planning as well as the IT-system. These three fields need a common key performance indicator basis for the evaluation because the performance indicators are linked to each other and the fields partially use the same indicators. The IPS²-ES plans and executes the service delivery for IPS². The quality of the delivery process is evaluated by the PMM because a not sufficient delivery process has to be planned and executed again. The quality data is also important for the evaluation of network partners in an IPS². Hence, this data is also used in the network evaluation. The results are used to reconfigure the network if a key performance indicator is beyond defined boundaries (see Fig. 5).

IV. IPS²-EXECUTION SYSTEM (Dorka) Due to the fact that the genetic algorithm used in the planning methods cannot be executed manually and the management of the fluctuations in the provider network have to be handled efficiently, the IPS²-Execution System (IPS²-ES) is developed. It serves as an automated tool and information system to coordinate the resources and suppliers for the delivery of all IPS² provided by on IPS² provider. Existing software solutions do not handle the extreme complexity of the dynamically changing partner networks and focus either only on service provision planning or on production planning. However, an integrated approach is needed for IPS². Still the information available in the distinct software systems are used by the IPS²-ES to fulfill its purpose (see Fig. 3).

PROJECT HISTORY Comprehensive offers, which comprise not only the product, but also additional value through complementary services, have been developed by the researchers of Collaborative Research Center CRC/Transregio 29 since 2006.

The required high availability as well as need for a real-time execution of the planning algorithms postulate the use of a high performance system that can be provided by cloud solutions. A plug-in system allows for integration of new services and partners as well as the connection to external systems (see Fig. 4).

III. IPS² ORGANIZATION AND PLANNING The operation phase includes the use of the IPS² as well as the delivery of (service) processes. For the execution of the delivery processes, several different resources are needed. Since an IPS² provider can not necessarily provide the capacity of all resources for the delivery of multiple IPS², he uses a network that integrates the IPS² provider with the IPS² customer and IPS² 3rd party suppliers (see Fig. 2). For each IPS², several partners from the provider network are selected to deliver the required processes. These partners form the IPS² network. For each single process partners from the IPS² network are selected to deliver this specific process as an IPS² delivery network. All networks are subject to change, for example when new partners enter or leave the provider network. [4] To define which resources are used to deliver which process, planning methods are required. Strategic capacity planning is used to ensure sufficient capacity to deliver all IPS². Operational resource planning is used
