The municipal solid waste system is a complex reverse logistic chain which comprises several optimisation problems. Although these problems are interdependent – i.e., the solution to one of restricts other they usually solved sequentially in related literature because each computationally problem. We address two tactical planning this by means Benders decomposition approach: determining locatio...

Waste processing in Bulota Village, Talaga Jaya District is very necessary considering the limited infrastructure and waste facilities surrounding area, which are unable to contain existing processing. This demonstrates paucity of garbage residents' lack sorting knowledge (organic inorganic). The impact that a lot paper plastic accumulates into useless waste. One management models 3R system, na...

In the static analysis of functional programs, pushdown flow analysis and abstract garbage collection push the boundaries of what we can learn about programs statically. This work illuminates and poses solutions to theoretical and practical challenges that stand in the way of combining the power of these techniques. Pushdown flow analysis grants unbounded yet computable polyvariance to the anal...

It is well accepted that Garbage Collection simpliies programming, promotes modularity, and reduces development eeort. However it is commonly believed that these advantages do not counteract the price that has to be paid: excesive overheads, possible long pause times, and the need of modifying existing code. Even though there exist publically available garbage collectors that can be used in exi...

As object oriented features are added to programming languages such as C demands upon dynamic memory allocation systems increase Prototyping languages such as Smalltalk and LISP have long rec ognized the impact of garbage collection on improving reliability and programmer productivity but providing garbage collection in C is hard because pointers are di cult to reliably identify Conser vative g...

An orthogonally persistent system maintains data beyond any program execution. The principle of persistence identification implies that persistence by reachability be used to determine which objects are to be maintained in the store. A particular execution may cause objects to become unreachable—garbage. Any efficient implementation of a persistent system must incorporate a garbage collector to...

The verification of memory safety–no program will crash when referencing memory–falls into two categories. A runtime system may enforce memory safety at a cost. Or, we may rely on error-prone programmers. Runtime overhead, most noticeably garbage collection, is undesirable in embedded or real-time systems. The frequency of collection points is not deterministic. Languages that rely on garbage c...

A number of possible approaches to automatic memory management in C++ have been considered over the years. Here we propose the reconsideration of an approach that relies on partially conservative garbage collection. Its principal advantage is that objects referenced by ordinary pointers may be garbage-collected. Unlike other approaches, this makes it possible to garbage-collect objects allocate...

We present some results and raise some issues regarding benchmarks for evaluating garbage collection in persistent distributed stores. We believe that such issues are relevant due to increasing research activity in this domain. Therefore, deening widely accepted benchmarks to evaluate the performance and impact of garbage collection solutions is urgent. Currently, the performance of garbage col...
