• Common mistakes in computing the nucleolus 

      Guajardo, Mario; Jörnsten, Kurt (Discussion paper;15/14, Working paper, 2014-04)
      Despite linear programming and duality have correctly been incorporated in algorithms to compute the nucleolus, we have found mistakes in how these have been used in a broad range of applications. Overlooking the fact ...
    • Explicit Solution Algorithms for Order and Price Postponement in Multi-periodic Channel Optimization 

      Azad Gholami, Reza; Sandal, Leif K.; Ubøe, Jan (Discussion paper;9/19, Working paper, 2019-09-09)
      Supply channels typically face uncertain and time-varying demand. Nonetheless, time-dependent channel optimization while addressing uncertain demand has received limited attention due to the high level of complexity of the ...
    • Solution Algorithms for Optimal Buy-Back Contracts in Multi-period Channel Equilibria with Stochastic Demand and Delayed Information 

      Azad Gholami, Reza; Sandal, Leif K.; Ubøe, Jan (Discussion paper;10/19, Working paper, 2019-09-09)
      We analyze the problem of time-dependent channel coordination in the face of uncertain demand. The channel, composed of a manufacturer and a retailer, is to address a time-varying and uncertain price-dependent demand. The ...
    • The Method of Leader’s Overthrow in Networks 

      Belik, Ivan; Jörnsten, Kurt (Discussion paper;1/16, Working paper, 2016-01-21)
      Methods for leader’s detection and overthrow in networks are useful tools for decision-making in many real-life cases, such as criminal networks with hidden patterns or money laundering networks. In the given research, we ...
