An algorithmic approach to multiobjective optimization with decision uncertainty
In real life applications, optimization problems with more than one objective function are often of interest. Next to handling multiple objective functions, another challenge is to deal with uncertainties conc...

Introduction
Mixed-integer optimization problems (MIP) appear in a variety of applications like in economics or engineering. One example is the uncapacitated facility location problem studied by Günlük, Lee, Weismantel [9]...

Conclusion
In this book, we have considered multiobjective mixed-integer convex optimization problems. We introduced basic definitions and concepts of multiobjective optimization. We derived a basic Branch-and-Bound algo...

Outlook and further possible improvements
In this Chapter, we discuss an extension of the proposed algorithm to the nonconvex case. Therefore, we introduce the concept of convex underestimators. As we have seen in Example 2.13, the assumption of conve...

A basic Branch-and-Bound algorithm for (MOMICP)
In this chapter, we introduce a basic algorithm for computing a ’good’ cover of the efficient set of (MOMICP). The algorithm illustrates the basic procedure that we use. The idea of this Branch-and-Bound algor...

Test instances and numerical results
We have implemented Algorithm 7 in MATLAB for p = 2. All tests have been run on an Intel(R) Core (TM) i7-6700K CPU @ 4.00GHz with 32GB RAM (2x DDR4-2399/16GB) on the operating system Microsoft Windows 10 Pro vers...

Enhancing Algorithm 1
In this chapter, we introduce modifications that enhance the basic Branch-and-Bound algorithm for (MOMICP), we introduced in Chapter 3. We follow different goals with these modifications. We would like to redu...
