Crypto‐coin hierarchies: social contestation in blockchain networks

In this article, I discuss the role of crypto‐coins (CCs) as an explicit response to the 2008 economic crisis. Drawing on networked social movement theory, I outline the tension between blockchain based currencies promoted as horizontal markets of technological innovation and the persistence of hierarchical authority within these networks. By examining the assumptions about authority and regulation that underpin the creation of CCs I argue that the cryptographic responses to the financial crisis understate the persistence of hierarchies in their claims to upset traditional monetary authority. As global networks, blockchain technology faces political challenges from regulators, hegemonic market actors and adherents devoted to particular CCs. Consequently, I draw parallels between CCs and networked social movements to argue that the emergence and proliferation of ‘altcoins’ presents a series of political challenges to the framing of CCs as disruptive technology. The innovative character of CCs relies on tacit and explicit assumptions about politics that social movement theory can help to explain. By examining the altcoins through the concepts of resource mobilization, framing and identity formation, I argue that the dynamics of offline social hierarchies persist and are magnified in the world of CCs.     

PLANNING AND SCHEDULING THE REPAIR SHOPS OF THE DEUTSCHE LUFTHANSA AG: A HIERARCHICAL APPROACH

To plan and schedule the repair shops for recoverable parts at Deutsche Lufthansa AC, we designed a hierarchical model consisting of two levels. The top level calculates the optimal number of parts in the system to guarantee a certain service level while minimizing the capital tied up in parts. Given this provision, the lower level schedules the repair of parts so that the service level is actually maintained. Using queuing theory, the solution gives special attention to the different hierarchical dependencies. Lufthansa has implemented the model for its repair shops of electronic parts. Their experience with the model is discussed briefly.     

The Revolt Against Cultural Authority: Power/Knowledge as an Assumption in Organization Theory

Foucault-inspired organization theory hasinterpreted the Enlightenment effort to make reason thefoundation for human freedom as a failure. Reason isseen as developing into disciplinary knowledge, which dominates modern organizations and theindividuals who live and work in them. In fact, theindividual s very identity is the means by which theindividual is enslaved. Knowledge is thus seen asnowhere separate from power. In this essay, I will usea concept of traditional authority to examineFoucault-inspired organization theory and itspower/knowledge conceptual framework in terms of theirethical and cultural implications. This will includeFoucault s influence on both the literature in criticalorganization theory and postmodern organization theory.My approach will highlight the Foucault-inspired misinterpretation of the effect of theEnlightenment on modern organizations, its rejection ofthe authority of the past as a basis for moral order,and its impossible attempt to find freedom through the destruction of cultural authority.     

CAPACITY AND PRODUCTION DECISIONS IN STOCHASTIC MANUFACTURING SYSTEMS: AN ASYMPTOTIC OPTIMAL HIERARCHICAL APPROACH

We present a new paradigm of hierarchical decision making in production planning and capacity expansion problems under uncertainty. We show that under reasonable assumptions, the strategic level management can base the capacity decision on aggregated information from the shopfloor, and the operational level management, given this decision, can derive a production plan for the system, without too large a loss in optimality when compared to simultaneous determination of optimal capacity and production decisions. The results are obtained via an asymptotic analysis of a manufacturing system with convex costs, constant demand, and with machines subject to random breakdown and repair. The decision variables are purchase time of a new machine at a given fixed cost and production plans before and after the purchase. The objective is to minimize the discounted costs of investment, production, inventories, and backlogs. If the rate of change in machine states such as up and down is assumed to be much larger than the rate of discounting costs, one obtains a simpler limiting problem in which the random capacity is replaced by its mean. We develop methods for constructing asymptotically optimal decisions for the original problem from the optimal decisions for the limiting problem. We obtain error estimates for these constructed decisions.     

A PAVEMENT MANAGEMENT DECISION SUPPORT SYSTEM

We present a pavement management expert system developed by the University of Wisconsin-Madison and implemented within a geographical information system for the Wisconsin Department of Transportation. The system uses pavement data regularly collected on the state's 12,000 miles of highway to assist engineers, planners, and budget analysts' management decisions about pavements to be included in 6-year improvement and 3-year maintenance programs. The system has a three-layer architecture. The lowest level suggests treatments for each of a large number of small segments of highway. The middle layer aggregates segments, suggests alternative treatments, and estimates the cost of each. The top layer prioritizes the projects and incorporates them into intermediate-range plans. The geographical information system environment enables integration of existing databases within the system using a topologically structured geographic database and specialized software.
