Abstract Nowadays among many evaluation methods, data envelopment analysis has widely used to evaluate the relative performance of a set of Decision Making Units (DMUs). Data Envelopment Analysis (DEA(is a mathematical tool for evaluating the relative efficiency of a set Decision Making Units (DMUs), with multiple inputs and outputs. Traditional DEA models treat with each DMU as a “black box" t...

A DAO is a blockchain-based system that enables people to coordinate and govern themselves mediated by set of self-executing rules deployed on public blockchain, whose governance decentralised (i.e., independent from central control).

In humanitarian relief operations (HRO), due to the excessive number of relief organizations, multiple organizational coordination is a demanding and complicated task. Considering such a problem, this paper proposes a two-phase mechanism to coordinate multiple heterogeneous relief organizations in a decentralized HRO logistics network. To address such a problem, first a bi-level mixed integer l...

Decentralized systems have emerged as an alternative to centralized approaches for dealing with dynamic requirements in new business models. These systems should provide mechanisms that contribute to flexibility and facilitate adaptation to changes in the environment. In this paper, we present two self-organization mechanisms for a decentralized service discovery system in order to improve its ...

Taking advantage of lower foreign tax rates using transfer pricing and taking advantage of lower production costs using offshoring are two strategies that global companies use to increase their profitability. Evidence suggests that firms employ these strategies independently. We study how global firms can jointly leverage tax and cost differences through coordinated transfer pricing and offshor...

Politicians and public managers continue to debate over whether to centralize or to decentralize departments, information systems and services. Shared service centers (SSCs) are gaining importance in public administration as a means to innovate, to reduce costs and to increase service levels. The SSC is a business model in which selected government functions are concentrated into a semi-autonom...

The thematic hypothesis of the paper is that both centralized and decentralized management schemes possess complementary features to induce successful project implementation. Centralized organizations are traditionally seen to promote control and coordination while the decentralized ones focus on autonomous units forming interactive and flexible networks ready to evolve over the execution of th...
