Randomization by minimization for unbalanced treatment allocation
Statistics in Medicine, 2009AbstractMinimization is a dynamic randomization technique that has been widely used in clinical trials for achieving a balance of prognostic factors across treatment groups, but most often it has been used in the setting of equal treatment allocations.

Fuzzy Random Redundancy Allocation Problems
2010Due to subjective judgement, imprecise human knowledge and perception in capturing statistical data, the real data of lifetimes in many systems are both random and fuzzy in nature. Based on the fuzzy random variables that are used to characterize the lifetimes, this paper studies the redundancy allocation problems to a fuzzy random parallel-series ...

Ex-Ante Fair Random Allocation
SSRN Electronic Journal, 2016When allocating indivisible objects, agents might have equal priority rights for some objects. A common practice is to break the ties using a lottery and randomize over deterministic allocation mechanisms. Such randomizations usually lead to unfairness and inefficiency ex-ante. We propose a concept of ex-ante fairness and show the existence of an agent-

Random allocations and probabilistic languages
1988This paper introduces a unified framework for the analysis of a class of random allocation processes that include: (i) the birthday paradox; (ii) the coupon collector problem; (iii) least-recently-used (LRU) caching in memory management systems under the independent reference model; (iv) the move-to-front heuristic of self-organizing search.

Random Arc Allocation and Applications
2002The paper considers a generalization of the well known random placement of balls into bins. Given n circular arcs of lengths ?1, ..., ?n we study the maximum number of overlapping arcs on a circle if the starting points of the arcs are chosen randomly. We give almost exact tail bounds on the maximum overlap of the arcs.

Randomization, Allocation, and Blinding
2012This chapter introduces a number of procedural issues in study design, that is, issues more relating to operations than to medicine or science.The issues of randomization, allocation, and blinding, as well as rules that regulate unblinding, help ensure or maximize the interpretability of the data that are eventually provided by the trial.
