In recent years, intelligent transportation system (ITS) techniques have been widely exploited to enhance the quality of public services. As one of the worldwide leaders in recycling, Taiwan adopts the waste collection and disposal policy named 'trash doesn't touch the ground', which requires the public to deliver garbage directly to the collection points for awaiting garbage collection. This study develops a travel time prediction system based on data clustering for providing real-time information on the arrival time of waste collection vehicle (WCV). The developed system consists of mobile devices (MDs), on-board units (OBUs), a fleet management server (FMS), and a data analysis server (DAS). A travel time prediction model utilizing the adaptive-based clustering technique coupled with a data feature selection procedure is devised and embedded in the DAS. While receiving inquiries from users' MDs and relevant data from WCVs' OBUs through the FMS, the DAS performs the devised model to yield the predicted arrival time of WCV. Our experiment result demonstrates that the proposed prediction model achieves an accuracy rate of 75.0% and outperforms the reference linear regression method and neural network technique, the accuracy rates of which are 14.7% and 27.6%, respectively. The developed system is effective as well as efficient and has gone online.

This study considers the manufacturing environments in which $m+1$ machines are configured as two-stage flexible flow shops with dedicated machines (F2DM). The F2DM scheduling problems arise naturally from practical production and fabrication systems, and they are classified into two categories, whose machine settings are antithetical to each other. In model 1, a single common bottleneck machine is installed at stage 1 and m parallel dedicated machines comprise stage 2. The second model has the m dedicated machines at stage 1 and the bottleneck machine at stage 2. Categorizing the literature according to the performance metrics, we survey the existing research results of the two models and propose several new solution procedures with improved computational complexity. The complexity results are summarized, and suggestions are made for future research.

In this paper, the problem of class formation and sequencing for multiple courses subject to a bottleneck
classroom with an ordered bi-criteria objective is studied. The problem can be modelled as a singlemachine
batch scheduling problem with incompatible job families and parallel job processing in batches,
where the batch size is family-dependent. For the minimisation of the number of tardy jobs, the strong
NP-hardness is proven. For the performance measure of the maximum cost, we consider single criterion
and bi-criteria cases. We present an Oðn2log nÞ algorithm, n is the number of jobs, for both cases. An
Integer Programming model as well as Simulated Annealing and Genetic Algorithm matheuristics to
solve a fairly general case of the bi-criteria problem is presented and computationally tested.

© 2015 Springer Science+Business Media New York This study addresses a relocation scheduling problem that corresponds to resource-constrained scheduling on two parallel dedicated machines where the processing sequences of jobs assigned to the machines are given and fixed. Subject to the resource constraints, the problem is to determine the starting times of all jobs for each of the six considered regular performance measures, namely, the makespan, total weighted completion time, maximum lateness, total weighted tardiness, weighted number of tardy jobs, and number of tardy jobs. By virtue of the proposed dynamic programming framework, the studied problem for the minimization of makespan, total weighted completion time, or maximum lateness can be solved in (Formula presented.) time, where (Formula presented.) and (Formula presented.) are the numbers of jobs on the two machines. The simplified case with a common job processing time can be solved in (Formula presented.) time. For the objective function of total weighted tardiness or weighted number of tardy jobs, this problem is proved to be NP-hard in the ordinary sense, and the case with a common job processing length is solvable in (Formula presented.) time. The studied problem for the minimization of number of tardy jobs is solvable in (Formula presented.) time. The solvability of the common-processing-time problems can be generalized to the m-machine cases, where (Formula presented.).

© 2016 Operational Research Society Ltd. This paper investigates the scheduling problem in a two-stage flexible flow shop, which consists of m stage-1 parallel dedicated machines and a stage-2 bottleneck machine, subject to the condition that n l jobs per type l∈1,..., m are processed in a fixed sequence. Four regular performance metrics, including the total completion time, the maximum lateness, the total tardiness, and the number of tardy jobs, are considered. For each considered objective function, we aim to determine an optimal interleaving processing sequence of all jobs coupled with their starting times on the stage-2 bottleneck machine. The problem under study is proved to be strongly NP-hard. An O(m 2 Π l=1 m n l 2) dynamic programming algorithm coupled with numerical experiments is presented.

This paper studies a problem of scheduling fabrication and assembly operations in a two-machine flowshop, subject to the same predetermined job sequence on each machine. In the manufacturing setting, there are n products, each of which consists of two components: a common component and a unique component which are fabricated on machine 1 and then assembled on machine 2. Common components of all products are processed in batches preceded by a constant setup time. The manufacturing process related to each single product is called a job. We address four regular performance measures: the total job completion time, the maximum job lateness, the total job tardiness, and the number of tardy jobs. Several optimality properties are presented. Based upon the concept of critical path and block schedule, a generic dynamic programming algorithm is developed to find an optimal schedule in O(n7) time.

This paper addresses scheduling n jobs in a two-machine flow shop to minimize the total completion time, subject to the condition that the jobs are processed in the same given sequence on both machines. A new concept of optimal schedule block is introduced, and polynomial time dynamic programming algorithms employing this concept are derived for two specific problems. In the first problem, the machine-2 processing time of a job is a step increasing function of its waiting time between the machines, and a decision about machine-1 idle time insertion has to be made. This problem is solved in O(n2) time. In the second problem, the jobs are processed in batches and each batch is preceded by a machine-dependent setup time. An O(n5) algorithm is developed to find an optimal batching decision.

This paper discusses a two-stage assembly-type flowshop scheduling problem with batching considerations subject to a fixed job sequence. The two-stage assembly flowshop consists of m stage-1 parallel dedicated machines and a stage-2 assembly machine which processes the jobs in batches. Four regular performance metrics, namely, the total completion time, maximum lateness, total tardiness, and number of tardy jobs, are considered. The goal is to obtain an optimal batching decision for the predetermined job sequence at stage 2. This study presents a two-phase algorithm, which is developed by coupling a problem-transformation procedure with a dynamic program. The running time of the proposed algorithm is O(mn + n(5)), where n is the number of jobs.

This paper addresses the total completion time minimization in a two-stage differentiation flowshop where the sequences of jobs per type are predetermined. The two-stage differentiation flowshop consists of a stage-1 common machine and m stage-2 parallel dedicated machines. The goal is to determine an optimal interleaved processing sequence of all jobs at the first stage. We propose an View the MathML source dynamic programming algorithm, where nk is the number of type-k jobs. The running time is polynomial when m is constant.

This paper investigates single-machine coupled-task scheduling where each job has two tasks separated by an exact delay. The objective of this study is to schedule the tasks to minimize the makespan subject to a given job sequence. We introduce several intriguing properties of the fixed-job-sequence problem under study. While the complexity status of the studied problem remains open, an O(n2) algorithm is proposed to construct a feasible schedule attaining the minimum makespan for a given permutation of 2n tasks abiding by the fixed-job-sequence constraint. We investigate several polynomially solvable cases of the fixed-job-sequence problem and present a complexity graph of the problem.

Single-machine scheduling is a classical combinatorial optimisation problem that has been widely addressed in literature. Considering the minimisation of the total weighted completion time with deterministic job processing times, the WSPT dispatching priority rule can simply yield the optimal solution. This study copes with the case of uncertain job processing times bound by the preassigned intervals, of which the processing time of each job could take any value between its corresponding lower and upper bounds. The objective is to minimise the maximum regret for any scenario generated within an instance. Given a set of jobs, an instance refers to the generation of the intervals of processing times and weights for jobs, whilst a scenario stands for the realisation of the job processing times generated within the intervals. Four heuristic algorithms utilising the lower and upper bounds are proposed in this paper. We develop the first heuristic with a pessimistic sense by considering only the upper bound, whilst the second one takes the optimistic approach using only the lower bound. The interval length is taken into account in the third heuristic, and the fourth one considers the position of the midpoint in relation to the mean of the midpoint of other jobs. We generated the instances by utilising an instance generation method available in the literature. The performance comparisons of the proposed algorithms in terms of the effectiveness and efficiency are then provided.

This study discusses two manufacturing environments, where m+1 machines are configured as two-stage flexible flow shops. In model 1, the bottleneck machine M0 is installed at stage 1, and the m dedicated machines constitute the stage 2. The second configuration has the m dedicated machines at stage 1 and the bottleneck machine M0 at stage 2. We present a concise survey of the existing results of the two models and report new algorithms and complexity status in the context of processing sequences fixed on the dedicated machines.
