Optimization for hierarchical multi-level planning systems using interaction prediction principle

This paper is concerned with the optimization of large-scale dynamic systems composed of interconnected subsystems. The decomposition and hierarchical multi-level approach with coordination is described for linear quadratic problem which has been available for socio-economic and production planning. In particular, we present a general solution algorithm for the two-level optimization using interaction prediction principle. A sample example for which the approach is applicable is illustrated.     

Coordination in operations: A taxonomy

This paper proposes a taxonomy of coordination study in operations. Its point of departure is the assumption that coordination study in operations always involves a “system” which can be a mathematical model, a software system, a business process or a game. A system is the unit of analysis in the taxonomy. In the taxonomy, systems are first divided into three categories depending on the type of coordination - coordination within operations, cross-functional coordination and inter-organizational coordination. Systems are further divided depending on how people in the organization behave, i.e., the perspective of organization. We propose three alternative perspectives of organization - single-person perspective, team perspective, and nexus-of-contract perspective of organization. Through a series of examples, we describe nine subcategories of systems.     

ORGANIZATIONAL STRUCTURING: AN EMPIRICAL ANALYSIS OF THE RELATIONSHIPS AND DIMENSIONS OF STRUCTURES IN CERTAIN FINNISH COMPANIES

The relationships of structure and structural factors at a general level are examined on the basis of data from a Finnish sample of mostly small and medium-sized industrial organizations. the sample, which consists of shoe and clothing firms, is homogeneous in terms of basic technology and industrial environment. the structural relationships are analysed from the point of view of size so that the interaction or concurrence of size and specialization is seen as a primary determinant of the systems of structural relationships. Some additional contextual variables are included in the analysis. Further, the factors or dimensions of structure reported are built on the basic variables of coordination and control. the factors are managerial supervision, the administrative component in general, including the clerical component, which is of particular importance, and impersonal mechanisms.     

Accommodating a Foreign Object: Federalism,coordination and performance management in the reform of German employment administration

Abstract

This paper uses the case of the reform of the German employment administration to explore the usage of performance management approaches within multi-level governance settings. It traces the adoption and accommodation of the performance management approach to govern the joint service centres (called ‘Jobcenter’) at the local level within the multi-level administrative coordination regime in Germany’s federal system. A contribution is made to nascent debates about the potential of managerial tools in systems of negotiated decision-making. The paper shows how performance management is adapted to the institutional logic of multi-level administrative coordination and serves as a facilitator of cross-level coordination.

Structural influences upon coordination and performance in multiteam systems

Building upon organizational design and boundary spanning and multilevel literatures, we propose a theoretical framework that extends previous work on the drivers of multiteam system (MTS) coordination and performance. Our proposal integrates aspects of functional process interdependence and different integration mechanisms used within MTSs to better elucidate how different coordination processes emerge. The framework exposes potential countervailing or confluent effects of coordination processes on performance and, thereby, reconciles seemingly incongruent findings regarding the effect of different approaches to coordination on MTSs performance. In addition, our framework helps managers consider the multilevel nature of MTS coordination processes in ways that assist them in selecting an approach to effectively address the coordination challenges inherent in these complex systems.     

Emergence of anti-coordination through reinforcement learning in generalized minority games

In this paper we propose adaptive strategies to solve coordination failures in a prototype generalized minority game model with a multi-agent, multi-choice environment. We illustrate the model with an application to large scale distributed processing systems with a large number of agents and servers. In our set up, agents are assigned responsibility to complete tasks that require unit time. They request servers to process these tasks. Servers can process only one task at a time. Agents have to choose servers independently and simultaneously, and have access to the outcomes of their own past requests only. Coordination failure occurs if more than one agent simultaneously requests the same server to process tasks at the same time, while other servers remain idle. Since agents are independent, this leads to multiple coordination failures. In this paper, we propose strategies based on reinforcement learning that minimize such coordination failures. We also prove a null result that a large category of probabilistic strategies which attempts to combine information about other agents’ strategies, asymptotically converge to uniformly random choices over the servers.

     

Coordination in global R&D organizations: An examination of the role of subsidiary mandate and modular product architectures in dispersed R&D organizations

International research and development (R&D) operations require a significant amount of coordination between the headquarters and the subsidiaries in order to integrate the dispersed activities in one final product. This article explores what mechanisms multinational companies (MNCs) use to coordinate their overseas R&D units. Based on a multiple case study involving nine MNCs with overseas R&D subsidiaries of varying mandates, we find that R&D sites with high technology and/or market orientation tend to be coordinated by informal mechanisms while sites with little technology and/or market orientation tend to be coordinated by formal mechanisms. Furthermore, it appears that this relationship is strongly affected by the product’s architecture: while rather complex R&D activities are conducted at the systems level and at sites with high technology orientation, less complex R&D activities are conducted at the component level at sites with low technology and market orientation. Finally, the findings suggest that modular product architectures have a coordinating effect in global R&D activities which have the power to lower firms’ overall coordination effort. The findings bear important implications for the effective coordination of MNCs’ international R&D subsidiaries.

Collaboration risk management in IT-enabled asymmetric partnerships: Evidence from telestroke networks

Information technology (IT)-enabled partnerships can unlock previously unattainable value propositions between organizations that have resource, capability, and other asymmetries by allowing larger organizations access to niche and local resources while providing smaller organizations access to enhanced resources and capabilities. However, recent studies have shown that many IT-enabled asymmetric partnerships often fail because the organizations do not effectively manage the involved collaboration risks. Most organizations focus on the strategic aspect of whether partners behave cooperatively or competitively, while paying scant attention to the operational aspect of bringing together partner contributions through coordination. To examine this problem, we report on a case study of two hub-spoke networks that used telemedicine to facilitate expertise sharing and decision making about stroke treatment at emergency departments in rural hospitals (spokes) based on information exchanges with remote neurologists at academic medical centers (hubs). As a result, we contribute to the inter-organizational information systems literature by explaining how organizations in IT-enabled asymmetric partnerships manage collaboration risks. We demonstrate how partners in such relationships perceive and approach strategic cooperation and operational coordination risks differently. We also explain how collaboration interactions change over time as the partners manage risks based on needs and resource endowments. Drawing on these findings, we provide guidance to organizations on how to manage sustainable IT-enabled asymmetric partnerships in general, and telestroke networks in particular.     

The coordination roles of relief organisations in humanitarian logistics

The number of organisations involved in relief work in general and humanitarian logistics specifically is large and increasing, creating new complexity. In this paper we analyse different types of coordination and roles in two case studies of the humanitarian cluster system based on its initial development and the Kenyan Post-election crisis. The different and unclear roles of the organisations create significant problems before and after cluster activation and deactivation. Individual organisations take on many roles in the cluster system and beyond it in terms of coordination. The clarity of the roles affects the need for and ease of coordination. We suggest a simple basic categorisation of roles as a starting point for developing this concept in the field of humanitarian logistics and connect this to coordination.     

Equilibria with coordination failures

This paper extends the literature on equilibria with coordination failures to arbitrary convex sets of admissible prices. This makes it possible to address coordination failures for cases with price indexation or more general price linkages between commodities. We introduce a new equilibrium concept, called quantity constrained equilibrium (QCE), giving a unified treatment to all cases considered in the literature so far. At a QCE the expected trade opportunities on supply and demand are completely determined by a rationing vector satisfying that the prevailing price system maximizes the value of the rationing vector within the set of admissible prices. When the set of admissible prices is compact, we show the existence of a connected set of QCEs. This set connects two trivial no-trade equilibria, one with completely pessimistic expectations concerning supply opportunities and one with completely pessimistic expectations concerning demand opportunities. Moreover, the set contains for every commodity a generalized Drèze equilibrium, being a QCE at which for that commodity no binding trade opportunities on both supply and demand are expected, and also a generalized supply-constrained equilibrium at which no binding constraints on demand opportunities are expected and for at least one commodity also not on supply. We apply this main result to several special cases, and also discuss the case of an unbounded set of admissible prices.     

Gains from international monetary policy coordination: Does it pay to be different?

In a two country world where each country has a traded and a non-traded sector and each sector has sticky prices, optimal independent policy in general cannot replicate the natural-rate allocations. There are potential welfare gains from coordination since the planner under a cooperating regime internalizes a terms-of-trade externality that independent policymakers overlook. If the countries have symmetric trading structures, however, the gains from coordination are quantitatively small. With asymmetric trading structures, the gains can be sizable since, in addition to internalizing the terms-of-trade externality, the planner optimally engineers a terms-of-trade bias that favors the country with a larger traded sector.     

Optimal coordination mechanisms in generalized principal–agent problems

The general principal–agent problem is formulated, in which agents have both private information and private decisions, unobservable to the principal. It is shown that the principal can restrict himself to incentive-compatible direct coordination mechanisms, in which agents report their information to the principal, who then recommends to them decisions forming a correlated equilibrium. In the finite case, optimal coordination mechanisms can be found by linear programming. Some basic issues relating to systems with many principals are also discussed. Non-cooperative equilibria between interacting principals do not necessarily exist, so quasi-equilibria are defined and shown to exist.

Hybrid Collaborative Arrangements: The welfare administration in Norway – between hierarchy and network

Abstract

This paper uses a survey to analyse how administrative executives perceive coordination following the reform of the Norwegian Labour and Welfare Administration. Applying a structural and cultural perspective, it examines the relationship between coordination mechanisms, cultural features and perceived coordination quality. The executives identify strongly with finding joint solutions and getting public organizations to work together. Coordination by hierarchy and networks co-exist, but the hierarchical dimension dominates. Vertical coordination is regarded as quite good, while horizontal coordination is seen as rather poor. The relationship between coordination mechanisms, cultural features and coordination quality are rather ambiguous and loose, however.     

The seven sisters: Snow whites,dwarfs or evil queens? A comparison of the official environmental policies of the largest oil corporations in the world

While environmental management of companies has become a topical issue both in theory and practice, the role of environmental policies in strategic environmental management has received little attention. The purpose of this paper is to study the environmental policies of the world's largest oil corporations in the context of general business goals and strategies, Ansoff's strategic posture analysis and Porter's competitive moves. Although there is some integration and coordination between the environmental policies and general business goals and strategies of oil companies, strategic environmental management is different from other strategic management. It seems to lag behind its business environment and does not utilise radical competitive moves. Further empirical research is needed to support these initial results and to find out reasons for this potential isolation.
